A symmetry analysis of differential equations plays an important role in discovering new solutions. In this article potential symmetries characterized by nonlocal ...

We investigate the planar ninth degree non-analytic Poincare systems which have center-focus equilibriums at the origins. Those systems could be changed into analytic systems ...

Perturbation–iteration method is generalized for systems of first order differential equations. Approximate solutions of Lotka–Volterra systems are obtained using the ...

We study a class of Padovan-like sequences that can be generated using special matrices of the third order. We show that terms of any sequence of this class can be expressed ...

We describe a new algorithm to compute singular point quantities for quasi analytic systems. It is transparent conceptually and efficient computationally with computer ...

We present the Mathematica package PlanarLinkages, which provides commands for constructing and visualizing planar linkages that draw a prescribed algebraic curve of genus 0, ...

A braid is a collection of strands which weave over and under one another. In Braids.m, a braid is described by a list {{m1, -m2 ..., mc},s} for a braid with s strands; where ...

This article contains a collection of Flash movies ready for use in a classroom, displaying various Flash-based instructional models on Mathematics and Mathematica learning. ...

Students will understand how to graph functions that represent stretches or inversions of given functions. Also, students will understand how changing each portion of an ...

A package for computing the generalized upper triangular decomposition of a matrix pencil A-zB as defined in (1). More information available at: http://www.cs.umu.se/~guptri ...
