分层流形上的伪微分算子

Pseudodifferential Operators on Stratified Manifolds

V. Nazaikinskii, A. Savin, B. Sternin

摘要:

我们考虑一类特殊的奇异流形,即分层流形,并描述了一类伪微分算子(PsiDO),它与此类流形上关于到地层的距离具有一阶退化的微分算子有关. (For这是一个具有孤立奇点的流形,这是一个Fuchs型退化。我们仅限于L^2空间中零阶算子的情形。在我们的方法中采用的PsiDO的定义使用归纳在流形中的层的数量。归纳过程自然涉及具有参数的PsiDO。

英文摘要:

We consider a specific class of manifolds with singularities, namely, stratified manifolds, and describe a class of pseudodifferential operators (PsiDO) related to differential operators with degeneration of first-order with respect to the distance to the strata on such manifolds. (For manifolds with isolated singularities, this is a Fuchs type degeneration.) We restrict ourselves to the case of zero-order operators in L^2 spaces. The definition of PsiDO adopted in our approach uses induction over the number of strata in the manifold. The induction process naturally involves PsiDO with parameters.
