Algebra of the Infrared with Curve-Valued Potential
Longfei Li
We study an extension of the algebra of the infrared to curve-valued potentials, focusing on the elliptic curve case. Given a finite configuration of points on an elliptic curve, w…

-structures on the additive decomposition of the Tate-Hochschild cohomology of a finite group algebra
Xiuli Bian, Longfei Li, Yuming Liu +3
Firstly, for a finite group algebra, we provide a computational framework for the Tate-Hochschild cochain complex in terms of the additive decomposition, by decompo…
