Results of Semigroup of Linear Operators Generating a Regular Weak*-continuous Semigroup

open access: yesEarthline Journal of Mathematical Sciences, 2022
This paper present results of $\omega$-order preserving partial contraction mapping generating a regular weak*-continuous semigroup. We consider a semigroup on a Banach space $X$ and $B:X^\odot\rightarrow X^*$ is bounded, then the intertwining formula was used to define a semigroup $T^B(t)$ on $X^*$ which extends the perturbed semigroup $T^B_0(t)$ on ...

Relative entropy and variational properties of generalized Gibbsian measures [PDF]

open access: yes, 2004
We study the relative entropy density for generalized Gibbs measures. We first show its existence and obtain a familiar expression in terms of entropy and relative energy for a class of ``almost Gibbsian measures'' (almost sure continuity of conditional ...

A Generalized Henry-Type Integral Inequality and Application to Dependence on Orders and Known Functions for a Fractional Differential Equation

open access: yesJournal of Applied Mathematics, 2014
We discuss on integrable solutions for a generalized Henry-type integral inequality in which weak singularity and delays are involved. Not requiring continuity or differentiability for some given functions, we use a modified iteration argument to give an

Investigating the influence of a weak continuous-wave-trigger on picosecond supercontinuum generation

open access: yesOptics Express, 2011
We numerically study the impacts of introducing a minute continuous-wave (CW) trigger on the properties of picosecond supercontinuum (SC) generation. We show that this simple triggering approach enables active control of not only the bandwidth, but more importantly the temporal coherence of SC.

Q-Learning for MDPs with General Spaces: Convergence and Near Optimality via Quantization under Weak Continuity

open access: yesCoRR, 2021
Reinforcement learning algorithms often require finiteness of state and action spaces in Markov decision processes (MDPs) (also called controlled Markov chains) and various efforts have been made in the literature towards the applicability of such algorithms for continuous state and action spaces.

Invariant Measures for Dissipative Dynamical Systems: Abstract Results and Applications [PDF]

open access: yes, 2012
In this work we study certain invariant measures that can be associated to the time averaged observation of a broad class of dissipative semigroups via the notion of a generalized Banach limit.

Generalized Fractional Integral Operators on Generalized Local Morrey Spaces

open access: yesJournal of Function Spaces, 2015
We study the continuity properties of the generalized fractional integral operator Iρ on the generalized local Morrey spaces LMp,φ{x0} and generalized Morrey spaces Mp,φ. We find conditions on the triple (φ1,φ2,ρ) which ensure the Spanne-type boundedness

Penalization method for a nonlinear Neumann PDE via weak solutions of reflected SDEs [PDF]

open access: yes, 2013
In this paper we prove an approximation result for the viscosity solution of a system of semi-linear partial differential equations with continuous coefficients and nonlinear Neumann boundary condition. The approximation we use is based on a penalization

Weak solutions of backward stochastic differential equations with continuous generator

open access: yesStochastic Processes and their Applications, 2014
We prove the existence of a weak solution to a backward stochastic differential equation (BSDE) $$ Y_t=ξ+\int_t^T f(s,X_s,Y_s,Z_s)\,ds-\int_t^T Z_s\,d\wien_s$$ in a finite-dimensional space, where $f(t,x,y,z)$ is affine with respect to $z$, and satisfies a sublinear growth condition and a continuity condition This solution takes the form of a triplet $(
