Rigidity of quadratic Poisson tori
Jesse Levitt, Milen Yakimov
We prove a rigidity theorem for the Poisson automorphisms of the function fields of tori with quadratic Poisson structures over fields of characteristic 0. It gives an effective me…

Quantized Weyl algebras at roots of unity
Jesse Levitt, Milen Yakimov
We classify the centers of the quantized Weyl algebras that are PI and derive explicit formulas for the discriminants of these algebras over a general class of polynomial central s…
