A novel method for calculating and visualizing the geodesic structure of space-time models is presented. By utilizing the symbolic computational power of Mathematica on a ...

The classical complex-variable method of Muskhelishvili for the solution of general plane elasticity problems is revisited. The boundary conditions are satisfied ...

An analytical method to calculate invariants is developed, based on the theory of complete systems of simultaneous linear first order partial differential equations. The ...

EinS is a package for Mathematica intended for calculations with indexed objects (e.g., tensors). The package automatically handles dummy indices and Einstein's summation ...

We consider algorithms for computing intersections and normalizers of subgroups in finitely generated nilpotent groups. In Glasby (1988a, b) and Glasby and Slattery (1990), ...

The solution to a system of n linear equations in n unknowns with integer coefficients is generally rational and not necessarily integer. For this reason, it would not appear ...

In order to describe the time evolution of an inhomogeneous collisionless plasma, the nonlinear Vlasov equation is solved perturbatively, using the subdynamics approach and ...

The aim of this work is to provide functions to manipulate the language generated by a given context-free grammar and solve the problem of recognition, i.e., to find out ...

An exact transfer-matrix formalism is developed for analyzing and solving problems in one-dimensional quantum mechanics. We show that with only three general-purpose ...

The propagation and reflection of arbitrarily shaped pulses on non-dispersive parallel conductors of finite length with user defined cross section is simulated employing the ...
