Maximal tori in $H H^{1}$ and the fundamental group

Benjamin Briggs, Lleonard Rubio y Degrassi

We investigate maximal tori in the Hochschild cohomology Lie algebra $H H^{1} (A)$ of a finite dimensional algebra $A$ , and their connection with the fundamental groups associated to p…

The A-infinity Centre of the Yoneda Algebra and the Characteristic Action of Hochschild Cohomology on the Derived Category

Benjamin Briggs, Vincent Gelinas

For A a dg (or A-infinity) algebra and M a module over A, we study the image of the characteristic morphism $χ_{M} : H H^{*} (A, A) \to E x t_{A} (M, M)$ and its interaction with the higher st…
