An introduction to monoid schemes
Chuck Weibel - Rutgers University
Location: Hill Center Room 705
Date & time: Wednesday, 09 February 2022 at 2:00PM - 3:00PM
If A is a pointed abelian monoid, its prime ideals make sense and form a topological space, analogous to Spec of a ring; the notion of a monoid scheme is analogous to the notion of a scheme in Algebraic Geometry. The monoid ring construction k[A] gives a link to geometry. In this talk I will give an introduction to the basic ideas, including toric monoid schemes, which model toric varieties.
