Dynamic-memory fractional calculus via generator-based memory construction: operational theory, semigroup structure, and applications

open access: yes
Most generalized fractional operators rely on prescribed memory kernels, restricting hereditary behavior to predefined forms and limiting flexibility in modeling diverse memory effects. Motivated by these limitations, this paper develops a generator-based framework for fractional calculus in which memory laws are systematically generated through a ...

Green index in semigroups : generators, presentations and automatic structures [PDF]

open access: yes, 2012
The Green index of a subsemigroup T of a semigroup S is given by counting strong orbits in the complement S n T under the natural actions of T on S via right and left multiplication.

Quantum stochastic operator cocycles via associated semigroups. [PDF]

open access: yes, 2005
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 ...

On the stability of quantum dynamical semigroups : a convergence analysis [PDF]

open access: yes, 2010
In this work we address the problems of state stabilization and convergence dynamics for finite-dimensional Quantum Dynamical Semigroups generators. We do so by building on the powerful notions of invariant and attractive quantum subsystems.
