Non self-adjoint correct restrictions and extensions with real spectrum
B. N. Biyarov, Z. A. Zakarieva, G. K. Abdrasheva
The work is devoted to the study of the similarity of a correct restriction to some self-adjoint operator in the case when the minimal operator is symmetric. The resulting theorem…
