Asynchronous Hybrid Systems with Jumps -- Analysis and Synthesis Methods
Synthesis Methods Analysis
2015/6/19
In this paper we show that the H-infinity synthesis problem for a class of linear systems with asynchronous jumps can be reduced to a purely discrete time synthesis problem. The system class considere...
A Discrete Weighted Helmholtz Decomposition and Applications to Non-overlapping Domain Decomposition for Saddle-point Maxwell Systems with Jumps in Coefficients

2012/8/8
We shall establish a discrete weighted Helmholtz decomposition in edge element
spaces, which is stable uniformly with respect to the jumps in the discontinuous weight
function. The stable decomposit...

2012/9/24
Up to now, the stability problem of mild solution for the impulsive stochastic system with Poisson jumps has not been solved. In this paper, based on fixed point theory, the stability of mild solution...

2011/9/16
Abstract: We consider the asymptotics of the invariant measure for the process of the spatial distribution of $N$ coupled Markov chains in the limit of a large number of chains. Each chain reflects th...

Abstract: Let $\Gamma$ denote the space of all locally finite subsets (configurations) in $\mathbb R^d$. A stochastic dynamics of binary jumps in continuum is a Markov process on $\Gamma$ in which pai...

2012/9/26
Based on the fixed point theory, the asymp totical stability of mild solution to impulsive stochastic partial differential equations with infinite delays and Markovian jumps is studied. In addition, s...
Comparison principles for integro-differential equations with L{é}vy operators - the case of spacial depending jumps -
Integro-differential equation L´ evy-Ito Operator Compari-son principle
2011/1/21
A comparison principle for the integro-differential equation with the L´evy operator corresponding to the spacial depending jump process is presented in this paper. The jump (x, z) at a point x...

SUSY Jumps Out Superspace Supersymmetric Standard Model
2011/3/3
The supersymmetric standard model (SSM) appears to be firmly grounded in superspace.For example, it would be natural to assume that all the physically important composite operators can be made by comb...

2011/2/21
We consider a second-order selfadjoint elliptic operator with an anisotropic di usion matrix having a jump across a smooth hypersurface. We prove the existence of a weight-function such that a Carlema...

We derive explicit formulas for the Mellin transform and the distribution of the exponential functional for Levy processes with rational Laplace exponent. This extends recent results by Cai and Kou o...

Escape from the potential well: competition between long jumps and long waiting times
potential well competition between long jumps long waiting times
2010/12/15
Within a concept of the fractional diffusion equation and subordination, the paper examines the
influence of a competition between long waiting times and long jumps on the escape from the poten-tial ...

We consider a random walk in a stationary ergodic environment
in Z, with unbounded jumps. In addition to uniform ellipticity and a bound on the tails of the possible jumps, we assume a condition of s...
