    題目: Standard and choiceless set-theoretic geology
    概要:
    The set-theoretic geology, which was initiated by Fuchs-Hamkins-Reitz, is a study of the global structure of all ground models of the universe. It attempts a study of the nature of the forcing method. In this talk, we present a framework of set-theoretic geology and basic results. Meanwhile, the standard geology is a research on ZFC, so the axiom of choice is assumed. However in the current set theory, the forcing method over choiceless model become a common tool. We also present the set-theoretic geology without the axiom of choice.

    題目: On extension of motivic cohomology to singular k-schemes
    概要:
    In this talk, I will talk about a recent new approach on the question of extending the motivic cohomology theory on smooth k-schemes to singular ones. This approach is very different from the approaches via cycles with modulus, in the sense of Binda-Saito or Kerz-Saito. I will briefly explain first what motivic cohomology is supposed to be, and sketch the ideas of the construction. I will give some results on the new objects, as well as several interesting potential applications of them. If time permits, I will also mention a few questions in progress. This is based on a joint work with Sinan Ünver.
