In the Hilbert space L A 2 ( I;E )( I:=[ a,b ),−∞ 0 ) , the maximal dissipative singular matrix-valued Sturm–Liouville operators that the extensions of a minimal symmetric operator with maximal ...
H. S. PERLMAN assumes that H is a self-adjoint operator, operating in Hilbert space. This assumption is not valid in quantum electrodynamics. H, like the other dynamical variables, then operates on ...
