On the MIT bag model in the non-relativistic limit. (English) Zbl 1373.81422
Summary: This paper is devoted to the spectral investigation of the MIT bag model, that is, the Dirac operator on a smooth and bounded domain of $${\mathbb{R}^3}$$ with certain boundary conditions. When the mass $$m$$ goes to $${\pm\infty}$$, we provide spectral asymptotic results.
