Wolfram|Alpha Notebook Edition combines the simplicity of Wolfram|Alpha with the computational capabilities of Mathematica for the best of both in a single, unified tool ...

This textbook gives a unified treatment of the solution of various linear equations that arise in science and engineering with examples. It is based on a course taught by the ...

Perturbative calculations in field theory at finite temperature involve sums over the Matsubara frequencies. Besides the usual difficulties that appear in perturbative ...

This paper proposes an implementation model for finite fields GF[mq], m prime, based on a hybrid architecture that integrates symbolic programming developed in Mathematica ...

The Löwdin alpha-function method, in which displaced orbitals are expanded in an infinite series of spherical harmonics, is implemented for Slater-type orbitals using a ...

Users can look forward to major new features in several areas: string maniipulation and support of foreign character sets; three-dimensional graphics and composite graphics; ...

Engineering analysis has undergone a dramatic change in the last 5 years. Computer programs with symbolic analysis, advanced interfaces and high-level languages have brought ...

The 1D Heisenberg spin model with anisotropy of the XXZ type is analysed in terms of the symmetry given by the quantum Galilei group gamma q(1). For a chain with an infinite ...

Short and accurate analytic formulas for the Seidel coefficients of gradient-index lenses with arbitrary radial refractive-index distributions have been obtained. Starting ...

Calculation of the higher order averaging equations of a non-linear oscillator is very tedious using the classical averaging method. This is also true for higher order normal ...
