摘要:
本文应用计算机代数方法研究具有挠率和规范场的弯曲流形上椭圆微分算子的谱渐近性。我们给出了非零挠率流形上非极小算子热核展开中第二系数 (E_2) 的完整表达式。这些表达式是针对任意维数 n 的一般流形情形以及对于 E_2 最重要的 n=2 情形计算得到的。计算是在个人计算机上借助用 C 语言编写的程序完成的。
英文摘要:
Computer algebra methods are applied to investigation of spectral asymptotics of elliptic differential operators on curved manifolds with torsion and in the presence of a gauge field. In this paper we present complete expressions for the second coefficient (E_2) in the heat kernel expansion for nonminimal operator on manifolds with nonzero torsion. The expressions were computed for general case of manifolds of arbitrary dimension n and also for the most important for E_2 case n=2. The calculations have been carried out on PC with the help of a program written in C.
