报告题目：Iterated Integrals and Relative Unipotent Completions
报告摘要：Iterated integrals are natural generalizations of usual line integrals. One of their defining properties is unipotency, from which a so-called unipotent completion of fundamental group can be constructed. A major application is a motivic Galois theory developed by Francis Brown for multiple zeta values. The algebraic structures and relations between these numbers will be discussed. To explain certain relations attached to modular forms, relative unipotent completions will also be introduced, with suggestive examples to illustrate the general principle.
