Contact Term Algebras and Dijkgraaf's Master Equation
Zhengping Gui, Si Li, Xinxing Tang
This paper is devoted to study integrable deformations of chiral conformal field theories on elliptic curves from the viewpoint of contact algebra. We introduce the relevant integr…

Trace Map on Chiral Weyl Algebras
Zhengping Gui
We construct a trace map on the chiral homology of chiral Weyl algebra for any smooth Riemann surface. Our trace map can be viewed as a chiral version of the deformed HKR quasi-iso…

Geometry of Localized Effective Theories, Exact Semi-classical Approximation and the Algebraic Index
Zhengping Gui, Si Li, Kai Xu
In this paper we propose a general framework to study the quantum geometry of -models when they are effectively localized to small quantum fluctuations around constant maps. Suc…
