The Use of Quantum Algebras in Quantum Gravity
Abstract
After a brief survey of the appearance of quantum algebras in diverse contexts of quantum gravity, we demonstrate that the particular deformed algebras, which arise within the approach of J.Nelson and T.Regge to 2+1 anti-de Sitter quantum gravity (for space surface of genus g) and which are basic for generating the algebras of independent quantum observables, are in fact isomorphic to the nonstandard q-deformed analogues U'q(son) (introduced in 1991) of Lie algebras of the orthogonal groups SO(n), with n linked to g as n=2g+2.
