Extensions of dissipative operators with closable imaginary part [PDF]

open access: yesOpuscula Mathematica, 2021
Given a dissipative operator \(A\) on a complex Hilbert space \(\mathcal{H}\) such that the quadratic form \(f \mapsto \text{Im}\langle f, Af \rangle\) is closable, we give a necessary and sufficient condition for an extension of \(A\) to still be ...

Extension of Algebraic Theories [PDF]

open access: yesProceedings of the American Mathematical Society, 1972
The algebraic theories of Lawvere are extended in a natural way to small complete categories. These categories exhibit not only the operations and identities, but some of the homomorphisms, functions, objects and constructions which are encountered when working within the algebraic categories associated with the theories.
