"Theory of motives with modulus and ramification theory".

 

Abstract: I will talk on the \emph{theory of motives with modulus} and its applications to ramification theory, based on joint works with B. Kahn, H. Miyazaki, T. Yamazaki, F. Binda, and K. R\"ulling. I will start with a brief review of Voevodsky's theory of motives, based on $\A^1$-invariance. The theory of motives with modulus aims at enlarging Voevodsky's theory in order to encompasses non-$\A^1$-invariant phenomena in a motivic framework such as wild ramification and connections with irregular singularities. As an application, it brings a new approach to ramification theory.
