Extensions of Peripheric Extended Twists and Inhomogeneous Lie Algebras
N. Aizawa
Abstract
Simple extensions of peripheric extended twists, introduced recently by Lyakhovsky and Del Olmo, are presented. Explicit form of twisting elements are given and it is shown that the new twists as well as peripheric extended twists are suitable to deform inhomogeneous Lie algebras such as isu(n), iso(n), (1+n) dimensional Schroedinger algebras and Poincare algebra.
