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 ...
The linear eigen- value problem for a non-self-adjoint operator is studied with two self-adjoint matrix Schrodinger operators. Sharp bounds on the number and type of unstable eigen- values in the ...
