B.1 center_lib

Library:
center.lib
Purpose:
computation of central elements of G-algebras and Q-algebras.
Author:
Oleksandr Motsak, motsak@mathematik.uni-kl.de.

Overview:
This is a library for computing the central elements and centralizers of elements in various noncommutative algebras. Implementation is based on algorithms, written in the frame of the diploma thesis by O. Motsak (advisor: Prof. S.A. Ovsienko, support: V. Levandovskyy), at Kyiv Taras Shevchenko University (Ukraine) with the title 'An algorithm for the computation of the center of noncommutative polynomial algebra'.

Support:
Forschungsschwerpunkt 'Mathematik und Praxis'

Procedures:

B.1.0.1 center  computes the generators of the center of a basering,
B.1.0.2 centralizer  computes the generators of the centralizer of f in a basering,
B.1.0.3 inCenter  checks the centrality of elements of list/ideal/poly l
B.1.0.4 inCentralizer  checks the commutativity wrt polynomial f of polynomials of list/ideal/poly l
