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 general scheme, suggested in [1] using a basis of an infinite-dimensional space and allowing to construct finite-dimensional orthogonal systems and interpolation ...

A new package, Thermath, for the automatic implementation of thermodynamic models was developed in the Mathematica programming language. Starting from an excess Gibbs free ...

An improved expression for the prediction of eclipse times in eccentric eclipsing binaries showing apsidal motion is presented. Truncated series expansions have been extended ...

The population balance model appears to be the best approach to model particulate systems where multiple heterogeneous reactions occur. This work demonstrates a mathematical ...

Many problems in plasma physics involve substantial amounts of analytical vector calculation. The complexity usually originates from both the vector operations themselves and ...

ODETaylorSeries generates the list{y1(x0)+y1'(x0)(x-x0)+y1''(x0)(x-x0)^2/2!+ ..., ..., yn(x0)+yn'(x0)(x-x0)+yn''(x0)(x-x0)^2/2!+ ... } containing the power series expansion ...

Analytic expressions are summarized and the intrinsic behaviour of the chord length distribution and the small-angle scattering correlation function are investigated for the ...

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 ...
