Extensions of peripheric extended twists and inhomogeneous Lie algebras

It is shown that the peripheric extended twists introduced recently by Lyakhovsky and Del Olmo has simple extensions. An explicit form of twisting elements is constructed 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 Schrِdinger algebras and the Poincaré algebra.
