We present the exact realization of extended Snyder model. Using similarity transformations, we construct realizations original and models. Finally, new $\kappa$-deformed

The Groseclose and Snyder (1996) model is one of the best-known models of vote buying in legislatures. Although the logic of the model is compelling, it is not clear that its key propositions, derived in a continuous set-up, hold in finite legislatures. This is an important issue because many real-world legislatures are small and should be modeled as finite in order to make predictions on coali...

In a recent paper, we have studied associative realizations of the noncommutative extended Snyder model, obtained by including Lorentz generators (tensorial coordinates) and their conjugated momenta. this extend result to also incorporate covariant realization $\kappa$-Poincar\'e spacetime. We obtain coproduct, star product twist in Weyl-ordered realization, first order noncommutativity paramet...
