Coinduction for Comodule Algebras

Explore the concept of coinduction for comodule algebras in this 44-minute lecture by Gisela Tartaglia from Universidad de la Plata. Learn about the construction of C_c(G)-comodule algebras from C(H)-comodule algebras for finite H, given a discrete group G and a subgroup H. Discover how this construction leads to a Morita equivalence between the crossed products of corresponding dual actions and recovers the group case. Gain insights into the consideration of C_c(G) as an algebraic (discrete) quantum group. Delve into the collaborative research conducted with Eugenia Ellis and Ana Karina González de los Santos on this topic.
