This paper concerns stochastic differential equationsdriven by G-Brownian motion under non-Lipschitz condition which is a much weakercondition with a wider range of applications. Stochastic averaging is establishedfor such non-Lipschitz SDEs where an averaged system is presented to replace theoriginal one in the sense of mean square. An example is presented to illustratethe averaging principle. 相似文献

In this note, hyperseparoids are introduced; hyperseparoids are to separoids as Tverberg’s theorem is to Radon’s theorem.
Also, a geometric representation theorem for acyclic k-separoids is presented which generalises that for separoids exhibited

In this paper,solutions of the following non-Lipschitz stochastic differential equations driven by G-Brownian motion:X_t=x+∫~t_0b(s,w,X_s)ds+∫~t_0h(s,ω,X_s)dBs+∫~t_0σ(s,ω,X_s)dB_s are constructed.It is shown that they have the cocycle property.Moreover,under some special non-Lipschitz conditions,they are bi-continuous with respect to t,x. 相似文献

Under linear expectation(or classical probability), the stability for stochastic differential delay equations(SDDEs), where their coeficients are either linear or nonlinear but bounded by linear functions, has been investigated intensively. Recently, the stability of highly nonlinear hybrid stochastic differential equations is studied by some researchers. In this paper,by using Peng's G-expectation theory, we first prove the existence and uniqueness of solutions to SDDEs driven by G-Brownian motion(G-SDDEs) under local Lipschitz and linear growth conditions. Then the second kind of stability and the dependence of the solutions to G-SDDEs are studied. Finally, we explore the stability and boundedness of highly nonlinear G-SDDEs. 相似文献

We prove that a square-integrable set-indexed stochastic process is a set-indexed Brownian motion if and only if its projections
on all the strict increasing continuous paths are one-parameter time-change Brownian motions. We present some applications. 相似文献

As we know,the representation theorem is one of the most important theorems foroperator semigroup theory.The representation theorem for exponentially bounded C-semigroup with dense range R(C) was given in [1 ] ,which was generalized to the casethat C does notnecessarily have dense range(see[2 ] ) .In this paper,more general caseis considered.We get a representation theorem for exponentially bounded mild C-exis-tence families.According to this,a simple proof of a construction theorem for C-s… 相似文献

It it shown that geometric morphisms between elementary toposes can be represented as certain adjunctions between the corresponding
categories of locales. These adjunctions are characterized by (i) they preserve the order enrichment and the Sierpiński locale,
and (ii) they satisfy Frobenius reciprocity. 相似文献
