Quantum Weyl algebras and reflection equation algebras at a root of unity

[摘要] We compute the center and Azumaya locus in the simplest non-abelian examples of quantized multiplicative quiver varieties at a root of unity: quantum Weyl algebras of rank N, and quantum differential operators on the quantum group GL(2). These examples illustrate in elementary terms much more general phenomena explored further in [8]. (C) 2020 Elsevier B.V. All rights reserved.
