Quantum perturbative solutions of extended Snyder and Yang models with spontaneous symmetry breaking
We propose ħ-expansions as perturbative solutions of quantum extended Snyder and Yang models, with ħ-independent classical zero-th order terms responsible for the spontaneous breaking of D=4 and D=5 de Sitter symmetries. In such models, with algebraic basis spanned by oˆ(D,1) Lie algebra generators,...
