Extensions of Peripheric Extended Twists and Inhomogeneous Lie Algebras

摘要

Simple extensions of peripheric extended twists, introduced recently byLyakhovsky and Del Olmo, are presented. Explicit form of twisting elements aregiven and it is shown that the new twists as well as peripheric extended twistsare suitable to deform inhomogeneous Lie algebras such as isu(n), iso(n), (1+n)dimensional Schroedinger algebras and Poincare algebra.
