SUMMARY:Koszul homomorphisms and universal resolutions in local algebra
DESCRIPTION:Speaker: Janina Letz\, University Bielefeld\n\nAbstract: I will define a Koszul property for a homomorphism of local rings $\varphi \colon Q \to R$. Koszul homomorphisms have good homological properties. Using $\mathrm{A}_\infty$-structures one can construct universal free resolutions of $R$-modules from free resolutions over $Q$, generalizing …
