Уважаемые коллеги!
 
По просьбе Георгия Игоревича Шарыгина сообщаю, что в эту пятницу в рамках работы "Китайско-российского математического центра" пройдёт онлайн семинар по топологии. Выступит Гуочжен Ван:

Guozhen Wang is a professor from Fudan University, Shanghai,  China. His 
main interest is algebraic topology. His main contribution lies in the 
computations of stable homotopy groups. He and collaborators has developed methods such 
as motivic deformation to push forward our knowledge of
stable homotopy groups of spheres and other spectra, which has many 
applications such as the classification of homotopy spheres.

Title: The last Kervaire invariant problem

Abstract:The Kervaire invariant is the obstruction for a framed cobordism 
class to have a homotopy sphere. It is important to know if this invariant 
is non-trivial when classifying homotopy spheres in a given dimension. We 
will give an account on recent joint work with Lin and Xu solving the last 
case of the Kervaire invariant problem in dimension 126.

Если вам интересно участие, пожалуйста, пишите Георгию Игоревичу gs...@yandex.ru или Александру Борисовичу Жеглову abz...@mail.ru 
 
С уважением, 
Дмитрий Гугнин
