Families of projective covers of path algebra representations.

Student-Run Algebraic Geometry Seminar

Speaker: Eric Babson, UC Davis
Location: 2240 MSB
Start time: Thu, Mar 15 2012, 1:10PM

We mark representations of the path algebra of a finite directed graph by a projective cover and consider the modules annihilated by the edge ideal. The resulting varieties are paved by fairly simple objects, and much of the geometry is carried by a 1-dimensional skeleton. (Joint work with Birge Huisgen-Zimmermann and Rekha Thomas)
