半经典区域的平衡态和本征函数估计

Equilibrium and eigenfunctions estimates in the semi-classical regime

Brice Camus

摘要:

我们建立本征函数估计,在半经典制度,与一个孤立奇点的临界能级。对于薛定谔算子,本征向量的渐近再分配与常规情况相同,除了在1维中出现临界点的集中。这一原则延伸到伪微分算子和极限措施是刘维尔措施,只要奇异性保持可积。

英文摘要:

We establish eigenfunctions estimates, in the semi-classical regime, for critical energy levels associated to an isolated singularity. For Schrödinger operators, the asymptotic repartition of eigenvectors is the same as in the regular case, excepted in dimension 1 where a concentration at the critical point occurs. This principle extends to pseudo-differential operators and the limit measure is the Liouville measure as long as the singularity remains integrable.
