Equivalence of diagonal contractions to generalized IW-contractions with integer exponents
Dmytro R. Popovych, Roman O. Popovych
We present a simple and rigorous proof of the claim by Weimar-Woods [Rev. Math. Phys. 12 (2000) 1505-1529] that any diagonal contraction (e.g., a generalized Inönü-Wigner contracti…

Lowest dimensional example on non-universality of generalized Inönü-Wigner contractions
Dmytro R. Popovych, Roman O. Popovych
We prove that there exists just one pair of complex four-dimensional Lie algebras such that a well-defined contraction among them is not equivalent to a generalized IW-contraction…
