A class of \(d\)-dimensional Dirac operators with a variable mass. (English) Zbl 1286.81077
Summary: A class of \(d\)-dimensional Dirac operators with a variable mass is introduced \((d\geq 2)\), which includes, as a special case, the 3-dimensional Dirac operator describing the chiral quark soliton model in nuclear physics, and some aspects of it are investigated.
