The Spectral Resolution of Some Non-Selfadjoint Partial Differential Operators
Let ffl and be Hilbert spaces, the set of all densely defined linear operators from to , and its subset of bounded ones. Let and σ ( T ) denote the adjoint, range, domain, closure and spectrum of T respectively. R i ( z ) will denote the resolvent ( …
