Query: Magnetic fields and boundary conditions in spectral and asymptotic
  analysis   This memoir is devoted to a part of the results from the author about two
topics: in the first part, the asymptotics of the low-lying eigenvalues of
Schr\"odinger operators in domains that may have corners, and in the second
part, the analysis of the thresholds of a class of fibered operators. The main
common object is the magnetic Laplacian, and the two parts are connected
through the study of model problems in unbounded domains.
