Optimal order finite element approximation for a hyperbolic‎ ‎integro-differential equation

‎Semidiscrete finite element approximation of a hyperbolic type‎ ‎integro-differential equation is studied. The model problem is‎ ‎treated as the wave equation which is perturbed with a memory term.‎ ‎Stability estimates are obtained for a slightly more general problem.‎ ‎These, based on energy method, are used to prove optimal order‎ ‎a priori error estimates.‎

Asymptotically Optimal Approximation and Numerical Solutions of Differential Equations

Given finite subset J ⊂ IR, and a point λ ∈ IR, we study in this paper the possible convergence, as h→ 0, of the coefficients in least-squares approximation to f(·+hλ) from the space spanned by (f(·+ hj)j∈J . We invoke the ‘least solution of the polynomial interpolation problem’ to show that the coefficient do converge for a generic J and λ, provided that the underlying function f is sufficient...

strong approximation for itô stochastic differential equations

in this paper, a class of semi-implicit two-stage stochastic runge-kutta methods (srks) of strong global order one, with minimum principal error constants are given. these methods are applied to solve itô stochastic differential equations (sdes) with a wiener process. the efficiency of this method with respect to explicit two-stage itô runge-kutta methods (irks), it method, milstien method, sem...

Optimal Belief Approximation

In Bayesian statistics probability distributions express beliefs. However, for many problems the beliefs cannot be computed analytically and approximations of beliefs are needed. We seek a ranking function that quantifies how “embarrassing” it is to communicate a given approximation. We show that there is only one ranking under the requirements that (1) the best ranked approximation is the non-...
