Dissipative operators and cohomology of operator algebras

Letters in Mathematical Physics, 1976
It is proved that an ultraweakly continuous completely dissipative operator on a W*-algebra A has a canonical form in terms of a completely positive map and a Hamiltonian provided that the cohomology groups of A with coefficients in a dual normal A-module are zero.

Fundamental solution of a dissipative operator [PDF]

, 1997
Summary: The fundamental solution \(K\) of a third-order operator \(L_\varepsilon\) is explicitly determined and various properties of \(K\) are analyzed. As an example of applications, the explicit solution of the initial-valued problem with arbitrary data is deduced.

Extensions of closed dissipative operators

Mathematical Notes of the Academy of Sciences of the USSR, 1973
Let B be a closed dissipative operator in a Hilbert space H with an arbitrary domain of definition. We will give a description of all closed (and, in particular, closed maximal) dissipative extensions\(\tilde B\) of B in terms of extensions\(\tilde W\) of a nonexpanding operator W associated with B.

On left invariant dissipative operators

Archiv der Mathematik, 1985
Let G be a locally compact group and let \((\mu_ t)_{t\geq 0}\) be a continuous semigroup of bounded measures with \(\| \mu_ t\| \leq 1\), \(\mu_ 0=\epsilon_ 0\). Let \((A_ t)\) be the corresponding semigroup of left invariant contractions \(f\to \mu_ t*f\) on \(C_ 0(G)\).

Dissipative Operators and Quasianalytic and Integral Vectors

Journal of Mathematical Sciences, 2001
The vector \(x\) is called quasianalytic, if the set \(C_{\{\|A^nx\|\}}\) consists of the quasianalytic functions. The author proves the following assertion. If the dissipative operator \(A\) has a dense set of quasianalytic vectors, then the operator \(A\) is maximally dissipative.
