Analysis of the essential spectrum of a third-order operator matrix in fermionic Fock space D. E. Ismoilova Bukhara State University
Abstract: The essential spectrum of a third-order operator matrix acting in the fermionic Fock space is studied. The first Schur complement corresponding to this operator matrix is constructed. The properties related to the negative eigenvalues of the first Schur complement are established. Website: https://us02web.zoom.us/j/8022228888?pwd=b3M4cFJxUHFnZnpuU3kyWW8vNzg0QT09
