摘要: Given a perturbed differential operator in a certain class, we construct an operator that is similar to the given one and has a much simpler structure of the perturbation. As a consequence, we obtain results on the asymptotics of the spectrum, convergence of the spectral decompositions, and the structure of the groups generated by the operators in question. In this talk, I will discuss recent results of this kind for one-dimensional Dirac operators and differential operators with an involution. The talk is based on the joint work with A. Baskakov and N. Uskova.
