等变Guillemin迹公式

An equivariant Guillemin trace formula

Peter Hochs, Hemanth Saratchandran

AI总结:

针对紧流形上的真、余紧群作用,提出Guillemin迹公式的等变推广,先发展分布迹的等变版本,为构造等变Ruelle动力ζ函数提供基础。

摘要:

Guillemin迹公式是紧流形上流拉回函数定义的算子的分布迹表达式。我们针对真、余紧群作用得到该公式的等变推广,其动机是同一作者另一篇论文中基于等变Guillemin迹公式构造的等变Ruelle动力ζ函数。为得到该公式,我们先发展Guillemin公式及其他场合出现的分布迹的等变版本。

英文摘要:

Guillemin's trace formula is an expression for the distributional trace of an operator defined by pulling back functions along a flow on a compact manifold. We obtain an equivariant generalisation of this formula, for proper, cocompact group actions. This is motivated by the construction of an equivariant version of the Ruelle dynamical $ζ$-function in another paper by the same authors, which is based on the equivariant Guillemin trace formula. To obtain this formula, we first develop an equivariant version of the distributional trace that appears in Guillemin's formula and other places.
