Opis A linear dynamical system is given by a (continuous linear) operator T on a topological vector space X; in most cases of interest, X is a Banach space or a Fréchet space. Important concepts in linear dynamics are that of a hypercyclic operator (which demands the existence of a dense orbit) and that of a chaotic operator (which demands, in addition, the existence of a dense set of periodic points). Apart from being interesting in its own right, the study of linear dynamical systems blends nicely methods from topological dynamics, functional analysis, operator theory and classical complex analysis. The course will be divided into two parts. In the first part (roughly one week) we will provide an introduction to the main concepts of linear dynamics. We will introduce and discuss the notions of hypercyclicity and linear chaos and provide criteria for deciding if a given operator is hypercyclic or chaotic. We will study in detail some important classes of operators like (weighted) backward shifts or composition operators. Necessary conditions for hypercyclicity will be based essentially on spectral theory. We will also study, in a parallel investigation, the dynamics of semigroups of operators, which has interesting applications. In the second part (roughly one week) we will discuss, depending on time, various advanced topics in linear dynamics. We will first derive some central results from linear dynamics: Ansari's theorem that any power of a hypercyclic operator is hypercyclic, the Bourdon-Feldman theorem that any somewhere dense orbit is everywhere dense, and the León-Műller theorem that any rotation of a hypercyclic operator is hypercyclic. We next study the existence of hypercyclic and chaotic operators on arbitrary topological vector spaces. Further topics will be taken from the following: the relatively new notion of a frequently hypercyclic operator, the existence of large (linear) subspaces of hypercyclic vectors for a given operator, and the existence of common hypercyclic vectors for a family of operators. The course will be based on [2], with additional material taken from [1]. A certificate can be obtained upon the successful completion of some exercises taken from the two books. References [1] F.

Opis 1. Rademacher series in rearrangement invariant spaces and real interpolation. 2. Rosenthal-type inequalities and the Kruglov operator. 3. A generalized Khintchine inequality in rearrangement invariant spaces. 4. Isomorphisms between rearrangement invariant spaces on the finite interval and on the semi-axis. Abstract. In the first part of these lectures we will focus on the behaviour of Rademacher functions (i.e., the Bernoulli sequence of independent, identically and symmetrically distributed random variables taking values .1) in rearrangement invariant (r.i.) spaces. In terms of interpolation theory of operators we define a one-to-one correspondence between r.i. spaces .close. to the space and Rademacher subspaces in them. This allows us to give a complete description of coordinate spaces of coeffcients of Rademacher sums from r.i. spaces. Some examples will be presented. In the second part the exposition we will discuss the Rosenthal-type inequalities and their various generalizations. We will present the sharp conditions under which the mentioned generalizations hold. The crucial tool here is based on the construction of Kruglov's operator developed recently. Among other applications we will discuss some variants of the classical Khintchine-Maurey inequality and isomorphisms between r.i. spaces on the finite interval and on the semi-axis.

Biogram wkładowcy Piotr Pragacz jest matematykiem pracującym od 1981 roku w IM PAN w Warszawie. W swych badaniach naukowych zajmuje się geometrią algebraiczną. Od 2000 roku kieruje Zakładem Algebry i Geometrii Algebraicznej IM PAN. Przedtem w latach 1977-1981 pracował na UMK w Toruniu. Piotr Pragacz studiował algebrę w Toruniu, geometrię algebraiczną w Warszawie, oraz kombinatorykę i geometrie enumeratywną w Paryżu u Alain Lascoux, którego uważa za swojego głównego nauczyciela. Habilitacja Piotra Pragacza dotyczyła geometrycznych i algebraicznych aspektów rozmaitości Schuberta oraz miejsc degeneracji morfizmów wiązek. Głównym jej wkładem było wprowadzenie i badanie P-ideałów miejsc degeneracji. Tej tematyce poświęcona jest książka [Book] napisana wspólnie z Williamem Fultonem. Spektrum zainteresowań matematycznych Piotra Pragacza obejmuje: geometrię algebraiczna ze szczególnym uwzględnieniem teorii przeciec: [15], [21], [32], [Book], [50]; algebraiczną kombinatoryką ze szczególnym uwzględnieniem funkcji symetrycznych: [13], [18], [34] oraz globalną teorię osobliwości ze szczególnym uwzględnieniem klas charakterystycznych rozmaitości osobliwych i wielomianów Thoma: [28], [38], [48], [49], [56], [57]. Terminy: "The Lascoux-Pragacz ribbon identity" (za W. Chen, 2004) oraz "The Sergeev-Pragacz formula" (za I. G. Macdonaldem w słynnej monografii "Symmetric Functions and Hall Polynomials", 1995), weszły na stale do terminologii algebraicznej. W 2000 roku Piotr Pragacz powołał do życia Seminarium Impanga, które stało się ogólnopolskim i międzynarodowym forum geometrii algebraicznej [O5].

Opis Celem tego semestralnego wykładu (30 godzin) jest wprowadzenie do klas charakterystycznych. Jest to ważne narzędzie współczesnej matematyki, niezbędne do pracy w geometrii i topologii, a użyteczne także w teorii liczb. Klasyczne "korzenie" klas charakterystycznych to: charakterystyka Eulera, indeksy pól wektorowych i twierdzenie Poincare-Hopfa, wzory Plückera dla krzywych płaskich, charakterystyka Eulera włókna Milnora, twierdzenia Riemanna-Rocha i Hurwitza dla krzywych, rachunek Schuberta. Współczesne podejście do klas charakterystycznych traktuje je jako elementy w pierścieniach kohomologii i ich analogonach. Na wykładzie omówione zostaną klasy Cherna zespolonych wiązek wektorowych, klasy Stiefela-Whitney'a, różne klasy charakterystyczne osobliwych rozmaitości analitycznych. Dowiedzione zostaną kluczowe twierdzenia o klasach charakterystycznych, a w szczególności twierdzenie Grothendiecka-Hirzebrucha-Riemanna-Rocha. Klasy charakterystyczne to miejsce gdzie spotyka się wiele dziedzin współczesnej matematyki: geometria, topologia, osobliwości, teoria reprezentacji, algebra i kombinatoryka. Jeśli chodzi o te dwie ostatnie dziedziny, to na wykładzie omówione zostaną podstawowe wiadomości o funkcjach Schura i wielomianach Schuberta. Jeśli czas pozwoli to końcówka wykładu poświęcona będzie wprowadzeniu do wielomianów Thoma osobliwości - ważnego działu współczesnej geometrii.

Tytuł Least Squares Method of American Option Pricing
Termin 8-22.10.2012
Wymiar godzin 15 godz.
Biogram wkładowcy Maciej Klimek is a professor of mathematics at Uppsala University in Sweden. He obtained his Ph.D. at the Jagiellonian University in 1981. Subsequently, he worked at Trinity College Dublin and then at the University College Dublin in Ireland until 1993, when he moved to Uppsala. At Uppsala University he obtained habilitation (associate professorship) in 1994 and then professorship in 2004. The subjects of his research range from multidimensional complex analysis and functional analysis to applied probability and finance. At present his research is focused on the use of block-frames in time series analysis and on American option pricing with multiple and non-Markovian underlying assets. Professor Klimek has written 32 mathematical research papers, most of which have been published in major international journals, and two books (for Oxford University Press and for Springer-Verlag in New York). According to the American Mathematical Society's MathSciNet Database, the quotation impact of Klimek's research publications amounts to 330 citations by 190 authors. His Erdös number is 3 and his Itô number is 4. Some of Klimek's articles have found applications in seismology (detection of deep low frequency earthquakes), risk analysis and actuarial science. He has also translated a mathematical monograph for Birkhäuser Verlag and has written several popular articles for the Polish large circulation monthly Charaktery. In the course of his career Maciej Klimek has been a visiting professor at various universities in Japan, USA, Ireland, Sweden, Poland, Canada, UK, France and Cameroon. He has refereed articles for 17 major international journals and he has evaluated research projects for national scientific bodies in USA, Canada and the Netherlands. He is an award-winning pedagogue whose portfolio includes supervision of 4 Ph.D. theses and about 40 M.Sc. dissertations.
Opis The objective of the course is to present a detailed study of computationally viable American option pricing methods based around the approximation of conditional expectations by finite dimensional projections. The course will start with a thorough review of main properties of stopping times and Snell envelopes, as well as their role in valuation of American options. Then, the geometry of the conditional expectation operators will be carefully examined. In particular we will look at the dependence on the underlying probability measure and at ranges of such operators. The latter are generally infinite-dimensional Hilbert lattices, so any feasible computational approach necessitates in some kind of approximation by finite dimensional subspaces. We will examine linearly dense sequences in spaces of square-integrable functions, using the Dobrushin-Minlos Theorem and other methods. Our study of the least squares method of option pricing will be based primarily on the ideas of Longstaff, Schwartz, Clément, Lamberton and Protter. The work of other researchers will also be briefly reviewed. Depending on the needs of the audience, the course will be given either in Polish or in English.
