The Casimir Invariants of Universal Lie algebra extensions via commutative structures
A B Yanovski
We consider the Casimir Invariants related to some a special kind of Lie-algebra extensions, called universal extensions. We show that these invariants can be studied using the equ…

Lie algebra extensions related with linear bundles of Lie brackets
A. B. Yanovski
We consider some special type extensions of an arbitrary Lie algebra , arising in the theory of Lie-Poisson structures over , where is the du…
