Accretive and nonnegative perturbations of an abstract analogy for the operator of the third boundary problem and corresponding variational problems(in Ukrainian)
In the paper the role of initial object is played by the positively definite operator L_0 acting in a Hilbert space H. The main object of the investigation is operator L B: It is interpreted as a perturbation of some proper extension of L0. Using methods of the extension theory the criteria of maxim...
