Vortex method for two dimensional Euler equations in bounded domains with boundary correction
The vortex method for the initial-boundary value problems of the Euler equations for incompressible flow is studied. A boundary correction technique is introduced to generate seco...

From formal numerical solutions of elliptic PDE's to the true ones
Abstract. We propose a discretization scheme for a numerical solution of elliptic PDE's, based on local representation of functions, by their Taylor polynomials (jets). This s...

Multivariate comonotonicity
In this paper we consider several multivariate extensions of comonotonicity. We show that naive extensions do not enjoy some of the main properties of the univariate concept. In o...

A modification of Shanks' baby-step giant-step algorithm
Abstract. I describe a modification to Shanks' baby-step giant-step algorithm for computing the order n of an element g of a group G, assuming n is finite. My method has the a...
