On the number of eigenvalues of a model operator in fermionic Fock space
On the number of eigenvalues of a model operator in fermionic Fock space
We consider a model describing a truncated operator H (truncated with respect to the number of particles) acting in the direct sum of zero-, one-, and two-particle subspaces of a fermionic Fock space a(L2(3)) over L2(3). We admit a general form for the "kinetic" part of the hamiltonian H, which …
