WEEKLY ACTIVITIES

The Mahler measure of exact polynomials and Deligne-Beilinson Cohomology
Báo cáo viên: Triệu Thu Hà - Đại học BK Hà Nội

Tóm tắt: The Mahler measure of polynomials was introduced by Mahler in 1962 as a tool to study transcendental number theory. Over time, numerous connections have been discovered between Mahler measures and objects in number theory, such as the special values of L-functions and the Riemann zeta function. To study these relationships, we employ cohomological tools, including Deligne-Beilinson cohomology and motivic cohomology. In this talk, I will first give an introduction to the Mahler measure of polynomials and highlight a fundamental result by Deninger from 1997. I will then briefly recall the definitions of Deligne-Beilinson cohomology and motivic cohomology. Finally, I will express the Mahler measure of an exact polynomial in arbitrarily many variables in terms of the Deligne-Beilinson cohomology.
