Zusammenfassung: Physical duality symmetries relate special limits of the various consistent string theories (Types I, II, Heterotic string and their cousins, including F-theory) one to another. By comparing the mathematical descriptions of these theories, one reveals often quite deep and unexpected mathematical conjectures. The best known string duality to mathematicians, Type IIA/IIB duality also called {it mirror symmetry}, has inspired many new developments in algebraic and arithmetic geometry, number theory, toric geometry, Riemann surface theory, and infinite dimensional Lie algebras. Other string dualities such as Heterotic/Type II duality and F-Theory/Heterotic string duality have also, more recently, led to series of mathematical conjectures, many involving elliptic curves, K3 surfaces, and modular forms.

Zusammenfassung: The conference is dedicated to professor Paulo Ribenboim on the occasion of his 80-th birthday. The conference concentrates on all aspects of number theory: elementary, analytic, algebraic, computational number theory; elliptic curves, modular forms, arithmetic algebraic geometry. It will start on October 4, 2008, at 8:30am and it will conclude on October 5, around noon.

Zusammenfassung: The conference is an activity of the Sonderforschungsbereich Mainz/Bonn/Essen on Periods, Moduli Spaces, and Arithmetic of Algebraic Varieties, and is supported by the Hausdorff Center for Mathematics (Bonn).

Zusammenfassung: The purpose of the workshop is to highlight the research of female number theorists.

Zusammenfassung: This workshop, sponsored by AIM and the NSF, has the goal of providing a description of $GL_3$ automorphic forms and their $L$-functions amenable to analytic number theorists and to explain the various approaches available to perform harmonic analysis on these spaces. A second objective will be to discuss the extension of some of the important tools existing in the $GL_2$ theory to the $GL_3$ context: a typical example is Kuznetzov's formula. A third objective will be to list some important problems known for $GL_2$ and to identify the main obstructions to the extension of these to $GL_3$: typical problems are non-vanishing problems for central values of L-functions and subconvexity problem. To achieve these goals we plan to bring together analytic number theorists and specialists from the theory of automorphic forms and related fields who are interested in analytic questions.

Zusammenfassung: The workshop will feature minicourses in hyperbolic geometry, quantum topology and number theory given by world renowned experts and is aimed at graduate students and recent PhD's. Support is available for the workshop and conference participants mainly in the form of housing. We also expect to provide partial travel support. Funding is provided by the NSF through an FRG grant. Detailed information about support, speakers and participants will be announced soon on the conference homepage.

Zusammenfassung: The conference will consist of a series of invited lectures concerning applications of the Stone-Cech compactification of the natural numbers and other discrete semi-groups to Algebra, Analysis and Combinatorics. The conference is also an opportunity to celebrate the immense contribution to this field that has been made by Dona Strauss on the occasion of her 75th Birthday. Talks are by invitation only. However the organizers would like to invite everyone who is interested to attend. The following have agreed to speak at the conference: Mathias Beiglbck (Vienna University of Technology, Wien); Vitaly Bergelson (Ohio State University); Wis Comfort (Wesleyan University); Garth Dales (University of Leeds); Stefano Ferri (Universidad de los Andes, Bogot); Chris Good (University of Birmingham); Neil Hindman (Howard University); Anthony To-Ming Lau (University of Alberta); Imre Leader (University of Cambridge); Matthias Neufang (Carleton University); Igor Protasov (Kyiv Unive

Zusammenfassung: The conference will cover the following subjects : ramification theory, vanishing cycles, rigid geometry, arithmetic D-modules, geometric and p-adic aspects of the Langlands Correspondence and related topics.
