LIPSCHITZ CLASSES OF A-HARMONIC FUNCTIONS IN CARNOT GROUPS CRAIG A. NOLDER The Hölder continuity of a harmonic function is characterized by the growth of its gradient. We generalize these results to solutions of certain subelliptic equations in domains in Carnot groups. Copyright © 2006 Craig A. Nolder.

ASYMPTOTIC BEHAVIOR IN STOCHASTIC FUNCTIONAL DIFFERENTIAL EQUATIONS OF NEUTRAL TYPE ZEPHYRINUS C. OKONKWO This paper deals with asymptotic behavior of the solution process of a class of neutral stochastic functional differential equations of Itô-Volterra form. Criteria for the existence of the solution process are outlined. Using the results of Corduneanu, Mahdavi, and Okonkwo, asymptotic behaviors of such solution processes (at +∞) are discussed.

Introduction We study the asymptotic behavior of the solutions to stochastic functional differential equations of the form with the random initial condition d(Vx)(t,ω) = (Ax)(t,ω)dt + φ ( t,x(t,ω) ) dz(t,ω) (1.1) x(0,ω) = x 0 ∈ R n . (1.2) Here and in the sequel, V and A will denote causal operators on the function space C(R + × Ω,R n ), which is the space of product measurable random functions x : R + × Ω → R n with continuous sample paths on every compact subset of R + . Ω isthesamplespace, with ω ∈ Ω. φ ∈ M 0 (R + × R n ,R n×k ), the space of n × k product measurable matrix-valued random functions with the property that ( ∫ T1 ∣ ω : sup φ ( t,x(t,ω) )∣ ) ∣ 2 dt < ∞ = 1, T 1 < ∞. (1.3) 0 0≤t≤T 1 The integral in (1.3) is assumed to be in the Lebesgue sense for each ω ∈ Ω. Wewill present a remark concerning the asymptotic behavior of (1.1), where the underlying space is L p loc (R + × Ω,R n ), 1 ≤ p ≤∞.
