Recently it was shown that by using two different realizations of ˆo(1,4) Lie algebra one can describe one-parameter standard Snyder model and two-parameter κ-deformed Snyder model. In this paper, by using the generalized Born duality and Jacobi identities we obtain from the κ-deformed Snyder model the doubly κ-deformed Yang model which provides the new class of quantum relativistic phase spaces. These phase spaces contain as subalgebras the κ-deformed Minkowski space-time as well as quantum ˜κ-deformed fourmomenta and are depending on five independent parameters. Such a large class of quantum phase spaces can be described in D=4 by particular realizations of ˆo(1,5) algebra, what illustrates the property that in noncommutative geometry different D=4 physical models may be described by various realizations of the same algebraic structure.
Finally, in the last Section we propose two new ways of generalizing Yang models: by introducing ˆo(1,3+2N) algebras (N=1,2…) we provide internal symmetries O(N) symmetries in
Kaluza-Klein extended Yang model, and by replacing the classical ˆo(1,5) algebras which describe the algebraic structure of Yang models by ˆo(1,5) quantum groups with suitably chosen nonprimitive coproducts.
