Tóm tắt: In the first talk, I will give a review of the construction of Berkovich analytic spaces and an explicit description of the Berkovich line. I also consider certain Berkovich analytic spaces for which l-adic Berkovich cohomology makes sense. In the second talk, I mention nearby and vanishing cycles of formal functions, as well as the comparison theorem for nearby cycles. As an application, I give proof of the l-adic integral identity conjecture for polynomials. Depending on the time, I may discuss this conjecture (still open) for formal power series which are not polynomials.
