Presentations for small reflection equation algebras of type A

We give presentations, in terms of the generators and relations, for the reflection equation algebras of type G L n and S L n , i.e., the covariantized algebras of the dual Hopf algebras of the small quantum groups of gl n and sl n . Our presentations display these algebras as quotients of the infinite-dimensional reflection equation algebras of types G L n and S L n by identifying additional relations that correspond to twisting the nilpotency and unipotency relations of the finite-dimensional quantum function algebras. The presentations are valid for appropriately defined integral forms of these algebras.
