Quantizing Derived Mapping Stacks
Ryan E. Grady
In this review we discuss several topological and geometric invariants obtained by quantizing -models. More precisely, we don't quantize the entire mapping stack of fields, but…

Parametrized L-infinity Spaces
Ryan E. Grady
Motivated by families of formal moduli problems, in this note we generalize the notion of L-infinity space by allowing sheaves of L-infinity algebras over any (reasonable) nilpoten…

Kazhdan's Property (T) for Graphs
Clara Brasseur, Ryan E. Grady, Stratos Prassidis
D. A. Kahzdan first put forth property (T) in relation to the study of discrete subgroups of Lie groups of finite co-volume. Through a combinatorial approach, we define an analogue…
