SECOND QUANTIZATION AND THE L<sup>p</sup>-SPECTRUM OF NONSYMMETRIC ORNSTEIN–UHLENBECK OPERATORS
SECOND QUANTIZATION AND THE L<sup>p</sup>-SPECTRUM OF NONSYMMETRIC ORNSTEIN–UHLENBECK OPERATORS
The spectra of the second quantization and the symmetric second quantization of a strict Hilbert space contraction are computed explicitly and shown to coincide. As an application, we compute the spectrum of the nonsymmetric Ornstein–Uhlenbeck operator L associated with the infinite-dimensional Langevin equation [Formula: see text] where A is the …
