Renormalizations in holomorphic field theories on Kähler manifolds
Minghao Wang, Junrong Yan
The divergence of Feynman graph integrals is one of the central issues in the study of perturbative quantum field theories. A rigorous formulation of these integrals usually requir…
Higher-dimensional Chiral Algebras in the Jouanolou Model and free-field realization
Zhengping Gui, Minghao Wang, Brian R. Williams
We appeal to the theory of Jouanolou torsors to model the coherent cohomology of configuration spaces of points in d-dimensional affine space. Using this model, we develop the oper…
On the renormalization and quantization of topological-holomorphic field theories
Minghao Wang, Brian R. Williams
Topological field theories and holomorphic field theories naturally appear in both mathematics and physics. However, there exist intriguing hybrid theories that are topological in…
Characterization of -Lie Derivations on Generalized Matrix Algebras
Xinfeng Liang, Minghao Wang, Feng Wei
The principal objective of this paper is to determine the structure of -Lie derivations () on generalized matrix algebras.It is shown that under certain mild assumption…
Feynman Graph Integrals on
Minghao Wang
We introduce a type of graph integrals which are holomorphic analogs of configuration space integrals. We prove their (ultraviolet) finiteness by considering a compactification of…
Feynman Graph Integrals on Kähler Manifolds
Minghao Wang, Junrong Yan
In this paper, we establish the convergence of Feynman graph integrals on closed real-analytic Kähler manifolds and uncover the structural mechanism underlying this convergence. Th…
