Traveling waves for the Keller-Segel system with Fisher birth terms
Chemotaxis Traveling waves Keller-Segel system Reaction diffusion systems Nonlinear stability
2015/7/14
We consider the traveling wave problem for the one dimensional Keller-Segel system with a birth term of either a Fisher/KPP type or with a truncation for small population densities. We prove that ther...
SEPARATION CUT-OFFS FOR BIRTH AND DEATH CHAINS。
On times to quasi-stationarity for birth and death processes
Probability the space independent index variable parameter the dirichlet conditions
2015/7/8
The purpose of this paper is to present a probabilistic proof of the well-known result stating that the time needed by a continuous-time finite birth and death process for going from the left en...
The Wartime Bridge Reliability Evaluation Model Based on Birth-and-Death Process
Wartime Bridge Reliability Evaluation Birth-And-Death Process
2013/1/30
At first, the concept of bridge reliability is given, followed with its mathematic model. Then, based on the analysis about the mechanism of the damage and repair of bridges, and the state diversion o...
Randomly Stopped Nonlinear Fractional Birth Processes
Fractional nonlinear pure birth processes Subordination fistable subordinator Fractional derivative First-passage time
2011/9/8
Abstract: We present and analyse the nonlinear classical pure birth process $\mathpzc{N} (t)$, $t>0$, and the fractional pure birth process $\mathpzc{N}^\nu (t)$, $t>0$, subordinated to various random...
Intertwining and commutation relations for birth-death processes
commutation relations birth-death processes
2010/11/15
Given a birth-death process on N with semigroup P_t and a discrete gradient D depending on a positive weight u, we establish intertwining relations of the form D P_t = Q_t D, where Q_t is the Feynman...
Stability on {0,1,2,...}^S: birth-death chains and particle systems
Stable polynomials birth-death chain negative association
2010/12/13
A strong negative dependence property for measures on {0, 1}n –stability – was recently developed in [5], by considering the zero set of the probability generating function. We extend this property to...
Ergodicity of Quasi-birth and death processes (I)
ergodicity quasi-birth and death process Markov chain matrix geometric solutions
2007/12/11
Quasi-birth and death processes with block tridiagonal matrices find many applications in various areas. Neuts gave the necessary and sufficient conditions for the ordinary ergodicity and found an exp...
