The notebook BrillouinZonePlotter.nb contains two scripts:1) myBZ[] generates 2D plots of any cross-section of the Brillouin Zones of any 3D crystal.2) myRed2Ext[] ...

Following an idea of Ozawa, we give a new proof of Kazhdan’s property (T) for SL(3, Z) by showing that 2 − /6 is a Hermitian sum of squares in the group algebra, ...

The package RestrictedPartitionFunctions provides functions for caculating the number of partitions of n in parts from cns. The function PartitionData[cns] returns parameter ...

The notebook WebSafeColors.nb defines the functions WebColorsPalette[] and WebColoringPalette[]. The function WebColorsPalette creates a palette that, when clicked on, ...

In this talk we would like to present MoMAMath, an on-line interactive software for mathematics learning, based on Mathematica and WebMathematica. The software has been ...

This article describes three Mathematica packages for the automatic calculation of one-loop Feynman diagrams: the diagrams are generated with FeynArts, algebraically ...

General expressions for matrix elements of the electric multipole operators in axial and triaxial harmonic oscillator basis are given. In each case we present algorithms ...

During the summer of 1995 the authors engaged in an undergraduate research program that investigated various conjectures about orthogonal polynomials. While exploring the ...

DensityPlot is probably one of the lesser-used of the built-in Mathematica graphics functions. DensityPlot takes a function of two variables, say x and y, and produces a ...

Recently, a very interesting Pascal-like triangle was described by Callan in a proposed problem for solution [1]. ... Like Pascal's triangle, this triangle has some nice ...
