Maximal tori in and the fundamental group
Benjamin Briggs, Lleonard Rubio y Degrassi
We investigate maximal tori in the Hochschild cohomology Lie algebra of a finite dimensional algebra , and their connection with the fundamental groups associated to p…
Locally complete intersection maps and the proxy small property
Benjamin Briggs, Srikanth B. Iyengar, Janina C. Letz +1
It is proved that a map of commutative noetherian rings that is essentially of finite type and flat is locally complete intersection if and only is proxy small…
Hochschild cohomology of twisted tensor products
Benjamin Briggs, Sarah Witherspoon
For a tensor product of algebras twisted by a bicharacter, we completely describe its Hochschild cohomology, as a Gerstenhaber algebra, in terms of the Hochschild cohomology of its…
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 and its interaction with the higher st…
