An algorithm for parallel processing the discrete nonlinear system for solving Fredholm integro-differential equations with twopoint boundary conditions on a PC cluster is considered. The cost of calculating the history terms is expensive and improvements are motivated by considering different architectures. The algorithm has been modified to minimize the communication overhead inherent in a di...

We present an AXIOM environment called JET for geometric computations with partial dierential equations within the framework of the jet bundle formalism. This comprises especially the completion of a given dierential equation to an involutive one according to the Cartan-Kuranishi Theorem and the setting up of the determining system for the generators of classical and non-classical Lie symmetrie...
