量子场论中的热核方法

Heat Kernel Approach in Quantum Field Theory

Ivan Avramidi

摘要:

简要介绍了量子场论和量子引力中的有效作用量方法,并描述了计算作用于紧致黎曼流形上向量丛截面上的二阶椭圆偏微分算子热核渐近展开的各种方法。我们考虑了无边界流形上的Laplace型算子和非Laplace型算子,以及有边界流形上的Laplace型算子和斜非光滑边界条件。

英文摘要:

We give a short overview of the effective action approach in quantum field theory and quantum gravity and describe various methods for calculation of the asymptotic expansion of the heat kernel for second-order elliptic partial differential operators acting on sections of vector bundles over a compact Riemannian manifold. We consider both Laplace type operators and non-Laplace type operators on manifolds without boundary as well as Laplace type operators on manifolds with boundary with oblique and non-smooth boundary conditions.
