Heat kernel asymptotics for Laplace type operators and matrix KdV hierarchy
摘要:
研究了黎曼流形上向量丛上拉普拉斯型微分算子的热核渐近性。特别地,这包括拉普拉斯算子作用于微分p-形式的情况。我们扩展了我们的结果得到较早的标量拉普拉斯算子和本闭公式与这些运营商的所有热不变量。作为另一个应用,我们提出了新的显式公式的矩阵Korteweg-de Vries层次。
英文摘要:
We study the heat kernel asymptotics for the Laplace type differential operators on vector bundles over Riemannian manifolds. In particular this includes the case of the Laplacians acting on differential p-forms. We extend our results obtained earlier for the scalar Laplacian and present closed formulas for all heat invariants associated with these operators. As another application, we present new explicit formulas for the matrix Korteweg-de Vries hierarchy.
