The Lévy–Khintchine type operators with variable Lipschitz continuous coefficients generate linear or nonlinear Markov processes and semigroups [PDF]

open access: yesProbability Theory and Related Fields, 2010
Ito's construction of Markovian solutions to stochastic equations driven by a Lévy noise is extended to nonlinear distribution dependent integrands aiming at the effective construction of linear and nonlinear Markov semigroups and the corresponding processes with a given pseudo-differential generator.

The discrete fragmentation equations : semigroups, compactness and asynchronous exponential growth [PDF]

open access: yes, 2012
In this paper we present a class of fragmentation semigroups which are compact in a scale of spaces defined in terms of finite higher moments. We use this compactness result to analyse the long time behaviour of such semigroups and, in particular, to ...

Convolution semigroups of states. [PDF]

open access: yes, 2011
Convolution semigroups of states on a quantum group form the natural noncommutative analogue of convolution semigroups of probability measures on a locally compact group.

A novel dual approach to nonlinear semigroups of Lipschitz operators [PDF]

open access: yesTransactions of the American Mathematical Society, 2004
The authors investigate the characterization of Lipschitzian semigroups in a Banach space. A Lipschitzian semigroup is a one-parameter semigroup of Lipschitz operators that is strongly continuous in the parameter. It is shown that a Lipschitzian semigroup can be isometrically embedded into a certain \(C_0\)-semigroup.

Results of semigroup of linear operators generating a nonlinear Schrödinger equation

open access: yesOpen Journal of Mathematical Analysis, 2022
In this paper, we present results of \(\omega\)-order preserving partial contraction mapping generating a nonlinear Schrödinger equation. We used the theory of semigroup to generate a nonlinear Schrödinger equation by considering a simple application of Lipschitz perturbation of linear evolution equations.

A photon transport problem with a time-dependent point source [PDF]

open access: yes, 2009
We consider a time-dependent problem of photon transport in an interstellar cloud with a point photon source modeled by a Dirac δ functional. The existence of a unique distributional solution to this problem is established by using the theory of ...

Fragmentation arising from a distributional initial condition [PDF]

open access: yes, 2010
A standard model for pure fragmentation is subjected to an initial condition of Dirac-delta type. Results for a corresponding abstract Cauchy problem are derived via the theory of equicontinuous semigroups of operators on locally convex spaces.

Feller semigroups, Lp-sub-Markovian semigroups, and applications to pseudo-differential operators with negative definite symbols [PDF]

open access: yes, 2001
The question of extending L-p-sub-Markovian semigroups to the spaces L-q, q > P, and the interpolation of LP-sub-Markovian semigroups with Feller semigroups is investigated.
