The main concepts related to the spectrum of a linear operator are presented, including the resolvent set, and the division of the spectrum into point, continuous and residual spectrum. A number of examples are discussed in detail. General properties of the spectrum are studied, with special ...
On the Spectrum of an Operator in Truncated Fock SpaceMathematics - Spectral Theory47G1081Q1047N50We study the spectrum of an operator matrix arising in the spectral analysis of the energy operator of the spin-boson model of radioactive decay with two bosons on the torus. An analytic ...

We study an extension of the classical Paley-Wiener space structure, which is based on bilinear expansions of integral kernels into biorthogonal sequences of functions. The structure includes both sampling expansions and Fourier-Neumann type series as special cases, and it also provides a bilinear ex...
