Resumen de Zariski cancellation problem for skew PBW extensions

Helbert Javier Venegas Ramírez

• A special question for noncommutative algebras is Zariski cancellation problem. In this thesis we establish cancellation for some special classes of algebras such as skew PBW extensions, some Artin--Schelter regular algebras and universal enveloping algebras of dimension three. In addition, we provide general properties for cancellation and we present a noncommutative analogues of a cancellation theorem for algebras of Gelfand-Kirillov dimension one.
