Valuation Rings over Function Field

STAG 112
Graduate Student Seminar

Speaker: Peyton Pfeiffer

In this talk, we will discuss algebraic concepts used to study function fields of one variable such as valuation rings. We will see that the valuation rings of a function field correspond to the places and discrete valuation functions of a function field. These aspects of function fields offer a more algebraic approach to important ideas in algebraic geometry such as the Riemann-Roch theorem. Read more.
