基于绝热膨胀理论的思想,给出了紧致黎曼流形上热核的各阶导数的渐近展开系数的一个新公式。这对于系统地理解系数是非常有用的,而且,通过只使用微积分的基本知识添加到公式中,可以明确地描述它们到任意高阶。
Based on the idea of adiabatic expansion theory, we will present a new formula for the asymptotic expansion coefficients of every derivative of the heat kernel on a compact Riemannian manifold. It will be very useful for having systematic understanding of the coefficients, and, furthermore, by using only a basic knowledge of calculus added to the formula, one can describe them explicitly up to an arbitrarily high order.
