The support properties of the super Brownian motion with random immigration Xρ1 are considered,where the immigration rate is governed by the trajectory of another super-Brownian motion ρ. When both the initial state Xρo of the process and the immigration rate process ρo are of finite measure and with compact supports, the probability of the support of the process Xρi dominated by a ball is given by the solutions of a singular elliptic boundary value problem.  相似文献

Weighted occupation time processes associated with the super-Brownian motions on hyperbolic spaces are investigated. Longtime behavior and a central limit type theorem for the processes are obtained. For all dimension d≥2, the right normings for two fluctuations are t and t1/2, and the limit results are the Riemannian measure and some centered Gaussian random measure, respectively.  相似文献

设C是Hilbert空间H中的非空子集,G是交换拓扑半群,S={Tt:t∈G}是C上渐近非扩张型半群,u()是S的有界殆轨道,则∫u(t+h)dμα(t)关于h∈G弱一致收敛于p,且当∩s∈GCO0{u(t):t≥s}C,T(t)对t∈G连续时,p是S的公共不动点.进一步,给出了u()的弱收敛定理,即limt∈Gu(t)存在当且仅当limt∈G(u(t+h)-u(t))=0,h∈G.  相似文献

Opial条件下渐近非扩张型半群殆轨道的遍历定理   总被引:1,自引:0,他引:1  
X是-Banach空间,(X,τ)是局部凸线性拓扑空间,C是X上的τ-序列紧凸集,S是C上的Γ类渐近非扩张型半群.首先给出了局部一致τ-Opial条件的概念,运用乘积拓扑网技巧得到了具有局部一致τ-Opial条件下空间X的新的收敛条件.然后利用该收敛条件得到了在局部一致τ-Opial条件下的,类渐近非扩张型半群殆轨道的遍历定理以及τ-收敛定理.结论是将已有结果由一致τ-Opial条件推广到局部一致τ-Opial条件,对空间X的要求进一步减弱,该结论是遍历定理在非一致凸空间中的延伸.  相似文献

证明“彐ξ∈(a,b),使f′(ξ)=0”是Rolle定理应用中重要题型,关键是寻找问题中的f(x),即作辅助函数f(x)。Lagrange中值定理也正是在找到这样的f(x)后利用Rolle定理来证明的。  相似文献

设G为半群,C为具FrEchet可微范数的一致凸Banach空间X的非空有界闭凸子集.(■)={T_t:t∈G}为C上到自身的渐近非扩张型半群,且F(■)非空.在本文中,我们证明了:对■的任一殆轨道u(·),■co{u(ts),t∈G}∩F(S)至多为单点集.进一步,对x∈C,∩_(s∈G)co{T_(ts)x,t∈G}∩F(■)非空当且仅当存在C到F(■)上非扩张压缩P,使得对任意t∈G,PT_t=T_tP=P,Px∈co{T_tx,t∈G}.这一结果不仅推广了许多已知结果,而且说明它们中的一些关键条件是不必要的.  相似文献
