摘要：
An essential problem in mathematical physics is to introduce and investigate operators perturbed by singular perturbations. Such operators are usually introduced with the aid of the theory of selfadjoint extensions of Hermitian operators. Berezansky and Brasche have proposed another viewpoint (see [3]) from which such objects are constructed by using operators in a Hilbert space chain (rigging). My report is concerned with operators that act from a positive space into a negative space of some Hilbert rigging. We investigate the generalized selfadjointness of such operators.
