An isoperimetric-type inequality for electrostatic shell interactions for Dirac operators
Abstract: In this article we investigate spectral properties of the coupling H +Vλ, where H = −iα ·∇ +mβ is the free Dirac operator in R3 , m > 0 and Vλ is an electrostatic shell potential (which depends on a parameter ...
