The ICMS seminar aims to present and disseminate advances in different fields of the contemporary fundamental and applied mathematics, and to promote new cutting edge directions in Mathematics. The seminar hosts scientific reports by collaborators and visitors of the ICMS, as well as colloquium-style lectures by invited speakers. The interdisciplinary features of the ICMS are reflected in the variety of topics covered in the seminar, ranging in algebraic and differential geometry, number theory, category theory, combinatorics, representation theory, mathematical physics, algebraic coding theory, etc. The venue is open to a wide audience, and the lectures are followed by time for interaction and discussion.

  • Tuesday, 13:00 (Sofia time)

  • Hall 403, Institute of Mathematics and Informatics at the Bulgarian Academy of Sceinces

  • Moderator: Valdemar Tsanov, IMI-BAS

Elliptic genus and applications, lecture by E. Lupercio

Ernesto Lupercio(IMI-BAS)

Friday, June 6, room 403, IMI-BAS. 16:00

In this course we will connect the theory of Topological modular forms with classical singularity theory. Other applications will be considered.

Group action on homogeneous spaces and applications in number theory, ICMS seminar talk by Georges Tomanov

In this talk, aimed at a general audience, we will describe recent results on the characterization of norm forms—a classical object in algebraic number theory—in terms of their values at integer points. These results answer natural questions and are related to still-open conjectures of Littlewood (from 1930) and of Cassels and Swinnerton-Dyer (from 1955). The proofs rely on studying the actions of maximal tori of algebraic groups on homogeneous spaces of arithmetic origin.
