From Wigner–Inönü Group Contraction to Contractions of Algebraic Structures
نویسنده
چکیده
The development of the notion of group contraction first introduced by E. Inönü and E.P. Wigner in 1953 is briefly reviewed. The fundamental role of the idea of degenerate transformations is stressed. The significance of contractions of algebraic structures for exactly solvable problems of mathematical physics is noticed.

Inönü - Wigner Contraction of Kac-Moody Algebras
We discuss Inönü-Wigner contractions of affine Kac-Moody algebras. We show that the Sugawara construction for the contracted affine algebra exists only for a fixed value of the level k, which is determined in terms of the dimension of the uncontracted part of the starting Lie algebra, and the quadratic Casimir in the adjoint representation. Further, we discuss contractions of G/H coset spaces, ...
متن کاملContractions of Lie Algebras and Algebraic Groups
Degenerations, contractions and deformations of various algebraic structures play an important role in mathematics and physics. There are many different definitions and special cases of these notions. We try to give a general definition which unifies these notions and shows the connections among them. Here we focus on contractions of Lie algebras and algebraic groups. 1. Contractions, degenerat...
متن کاملNew determinantal formulae for the Casimir operators of inhomogeneous pseudo-unitary Lie algebras and their Inönü-Wigner contractions
For the inhomogeneous pseudo-unitary Lie algebras Iu(p, q) a determinantal method to compute the Casimir operators is given, independently of the traditional analysis of the enveloping algebra. This procedure is extended to contractions of Iu(p, q) isomorphic to an extension by a derivation of the inhomogeneous special pseudo-unitary Lie algebras Isu(p − 1, q), providing an alternative analytic...
متن کاملThe Shape of Uterine Contractions and Labor Progress in the Spontaneous Active Labor
Background: Dystocia is the most common indication of primary cesarean section. The most common cause of dystocia is uterine dysfunction. In prolonged labor, more attention is usually paid to the fetus and pelvis rather than to the role of uterine contractions in a delivery. Therefore, we decided to determine the relationship between the labor progress and uterine contractions shapes.Methods: I...
متن کاملSome Comments on Contractions of Lie Algebras
We prove that two of the counterexamples of contractions inequivalent to a generalized Inönü-Wigner contraction exhibited in [1] are incorrect. An alternative characterization of general contractions is proposed.
