- W2181554098 abstract "By adopting the framework developed in [1], based on the behaviour of the representation operators induced by the contraction conditions, we determine the Inonu-Wigner contraction of the Lie algebra su(2) to the tridimensional Heisenberg algebra h1 with respect to a nilpotent subalgebra, as well as its inverse expansion. The contraction and expansion solutions emerge directly from the embedding of su(2) in the enveloping algebra of hl, U(hl), via the behavior of the su(2) representation operators in terms of the U(hl) representation operators and of the contraction parameter. In the case considered here, the same embedding can be solved by using the coherent state representation." @default.
