title: Generation of quasi-random (LPτ) vectors for parallel computation

description: Abstract A procedure for generating sequences of LP_τvectors that are uniformly distributed in the multi-dimensional unit cube is presented here together with its implementation in ANSI-C. The high performance and the efficiency of the generating algorithm make sequences of LP_τvectors preferable to cope with some problems traditionally associated with Monte Carlo methods. The suggested implementation uses the recurrent algorithm whenever it is possible, or executes the algorithm producing LP_τv...

title: Killing – An algebraic computational package for Lie algebras

description: Abstract The Killing package is a set of algebraic computational procedures to manipulate elements of representation theory for classical, exceptional and deformed Lie algebras. It is divided in two major parts: (1) The Roots & Weights formalism to classify all semisimple Lie algebras and their irreducible representations, and (2) The Gelfand–Tsetlin method to construct explicitly the irreducible representations of classical Lie algebras, including the deformed unitary Lie algebras. Title of program: KILLING Catalogue Id: ADLX_v1_0 Nature of problem Symmetry has been a very important fundamental principle underlying human knowledge about our physical world. Among several mathematical formulations of symmetry, the Lie algebras and their corresponding Lie groups are probably the ones most explored. They were discovered by Sophus Lie and Wilhelm Killing during the last two decades of the 19th century. Lie's work on Lie groups was inspired by Galois' work in 1832 in which he discovered the finite groups. Independently, Killing had started a cla ...

Advantages of the method are its capability to run with a small number of particles, its accurate treatment of advection and the absence of a need for velocity space meshes. The major inconvenience of that method is its inefficiency to present the behaviour of high velocity particles in near Maxwellian plasmas. These ki ...
