Rationing with baselines: the composition extension operator

, 2013
We introduce a new operator for general rationing problems in which, besides conflicting claims, individual baselines play an important role in the rationing process. The operator builds onto ideas of composition, which are not only frequent in rationing,

Recursive process definitions with the state operator [PDF]

, 1991
We investigate the defining power of finite recursive specifications over the theory with + (alternative composition) and • (sequential composition) and λ (the state operator) over a finite set of states, and find that it is greater than that of the same

Composition operators isolated in the uniform operator topology

, 1981
It is is shown that ϕ \phi is an analytic map of the disc | z | > 1 \left | z \right | > 1 into itself such that ϕ \phi has radial limits ...

Operators commuting with complex symmetric weighted composition operators on H 2

Concrete Operators
In this article, we initially study when an anti-linear Toeplitz operator is in the commutant of a composition operator. Primarily, we investigate weighted composition operators Wg,ψ{W}_{g,\psi } commuting with complex symmetric weighted composition ...

Topologizability and Related Properties of the Iterates of Composition Operators in Gelfand-Shilov Classes

[EN] We analyse the behaviour of the iterates of composition operators defined by polynomials acting on global classes of ultradifferentiable functions of Beurling type which are invariant under the Fourier transform.

Compact Composition Operators and Iteration

Journal of Mathematical Analysis and Applications, 1993
Let \(X\) be an \(F\)-space of analytic functions in a domain \(\Omega\) of the complex plane, and let \(\varphi\) be an analytic function mapping \(\Omega\) into itself, such that \(C_ \varphi f:= f\circ\varphi\) defines a compact operator in \(X\). \textit{J.

Quantum stochastic operator cocycles via associated semigroups. [PDF]

, 2007
A recent characterisation of Fock-adapted contraction operator stochastic cocycles on a Hilbert space, in terms of their associated semigroups, yields a general principle for the construction of such cocycles by approximation of their stochastic ...
