SUMMARY:Cartier algebras through the lens of p-families
DESCRIPTION:Speaker: Anna Brosowsky\, University of Michigan\n\nA Cartier subalgebra of a prime characteristic commutative ring R is an associated non-commutative ring of operators on R that play nicely with the Frobenius map. When R is regular, its Cartier subalgebras correspond exactly with sequences of ideals called F-graded systems. One special subclass of …

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 …

SUMMARY:Multiplicities in flat local extensions
DESCRIPTION:Speaker: Cheng Meng\, Purdue\n\nWe introduce the notion of strongly Lech-independent ideals as a generalization of Lech-independent ideals defined by Lech and Hanes, and use this notion to derive inequalities on multiplicities of ideals. In particular we prove that if (R,m) and (S,n) are Noetherian local rings of the same …

SUMMARY:Counterexamples for Several Open Problems on the Vanishing of Ext and Tor
DESCRIPTION:Speaker: Justin Lyle\, University of Arkansas\n\nLet R be a commutative Noetherian local ring. We discuss several properties R may satisfy that behave well under certain operations, and provide a general construction for producing local rings with some nice local behavior that satisfy one such property but not another. Through our methods we …

SUMMARY:Tame ramification and compatible ideals
DESCRIPTION:Speaker: Anne Fayolle\, University of Utah\n\nWe introduce a notion of tame ramification for general finite covers. When specialized to the separable case, it extends to higher dimensions the classical notion of tame ramification for Dedekind domains and curves. However, when applied to the Frobenius map, it naturally yields the notion of …

SUMMARY:Representations of hereditary algebras
DESCRIPTION:Speaker: Henning Krause\, University Bielefeld\n\nHereditary algebras and their representations became popular when Gabriel introduced quivers and their representations in the 1970s. My talk will present some of the highlights of this theory, without restricting to algebras arising from quivers.
