We develop the concept of operators in Hilbert spaces which are similar to their adjoints via antiunitary operators, the latter being not necessarily involutive. We discuss extension theory, refined polar and singular-value decompositions, and antilinear eigenfunction expansions. The study is motivated by physical symmetries in quantum mechanics with non-self-adjoint operators.

The Pauli equation with complex boundary conditions

We consider one-dimensional Pauli Hamiltonians in a bounded interval with possibly non-self-adjoint Robin-type boundary conditions. We study the influence of the spin–magnetic interaction on the

Complex symmetric completions of partial operator matrices

ABSTRACT We study complex symmetric completions of a partial operator matrix which specified part is an operator from a Hilbert space into a closed proper subspace. We give necessary and sufficient

Spectral Theory and Differential Operators

This book gives an account of those parts of the analysis of closed linear operators acting in Banach or Hilbert spaces that are relevant to spectral problems involving differential operators, and

A filler for a continuous cigarette filter rod is formed by feeding a wide band of filaments of filter material on to a slower moving surface, to which suction is applied so that the band is axially
