Counting Zeros of Holomorphic Functionsand (Math Ann 342(1):177–243, 2008. .) we obtained such a generalization, by weakening the regularity assumptions on the functions .. However, due to some logarithmic losses, we were not quite able to recover Hager’s original result, and we still had a fixed domain Γ with smooth boundary.

Distribution of Eigenvalues for Semi-classical Elliptic Operators with Small Random Perturbations, Rrding to Weyl’s law “most of the time” in a probabilistic sense. The first three sections are devoted to the formulation of the results and in the last section we give an outline of the proof that will be carried out in Chaps. . and ..

Book 2019al subject going back to H. Weyl of more than a century ago..In the last decades there has been a renewed interest in non-self-adjoint differential operators which have many subtle properties such as instability under small perturbations. Quite remarkably, when adding small random perturbations to s

Resolvent Estimates Near the Boundary of the Range of the Symbol already described a very precise result of W. Bordeaux Montrieux in dimension 1. Here we consider a more general situation; the dimension can be arbitrary and we allow for more degenerate behaviour. The results will not be quite as precise as in the one-dimensional case.
