Applications to Quantum Field Theory,Models of quantum field theory are sources of numerous mathematical theories. Thus, in particular, the theory of singular perturbations is closely related to problems of quantum field theory.

These claims are powerful tools in contemporary debates over who we are, who we want to be and what we should do. Drawing on a wid

Typical examples of such expressions are Schrodin­ ger operators with O-potentials (-~ + AD) and Hamiltonians in quantum field theory with perturbati
