چکیده
1. Basic Assumptions. Assume that (i) {Tt} is a strongly-continuous semigroup of bounded linear operators on the Banach space B = C0(I) = { f continuous on I = [0, 1] : f(0) = f(1) = 0 } (ii) If f(x) ≥ 0 and f ∈ B, then Ttf(x) ≥ 0 and Ttf(x) ≤ maxy∈I f(y). In general, the infinitesimal generator of a strongly-continuuous semigroup of linear operators Tt on any Banach space B is defined by Af = lim h→0 (Thf − f)/h (1.1)

متن کاملThe streamline diffusion method with implicit integration for the multi-dimensional Fermi Pencil Beam equation
We derive error estimates in the appropriate norms, for the streamlinediffusion (SD) finite element methods for steady state, energy dependent,Fermi equation in three space dimensions. These estimates yield optimal convergencerates due to the maximal available regularity of the exact solution.High order SD method together with implicit integration are used. The formulationis strongly consistent...
متن کاملBoundary Dynamics of a Two-dimensional Diffusive Free Boundary Problem
Numerous models of industrial processes such as diffusion in glassy polymers or solidification phenomena, lead to general one-phase free boundary value problems with phase onset. In this paper we develop a framework viable to prove global existence and stability of planar solutions to one such multidimensional model whose application is in controlled-release pharmaceuticals. We utilize a bounda...
متن کاملNon-degeneracy of Wiener Functionals Arising from Rough Differential Equations
Abstract. Malliavin Calculus is about Sobolev-type regularity of functionals on Wiener space, the main example being the Itô map obtained by solving stochastic differential equations. Rough path analysis is about strong regularity of solution to (possibly stochastic) differential equations. We combine arguments of both theories and discuss existence of a density for solutions to stochastic diff...
متن کامل3 On L 1 - distance between first exit times from two regions ∗ †
First exit times from regions and their dependence on variations of boundaries are discussed for diffusion processes. The paper presents an estimate of L1-distance between exit times from two regions via expectations of exit times. Abbreviated title: On L1-distance between first exit times It is known that first exit times from a region for smooth solutions of ordinary equations does not depend...
