Hello, Roughly speaking, a quantum group is an algebraic structure which is obtained by means of a deformation of a group. There rigorous definition is here: https://ncatlab.org/nlab/show/quantum+group Official reference to quantum groups: Kassel, Christian (1995), Quantum groups, Graduate Texts in Mathematics, 155, Berlin, New York: Springer-Verlag, doi:10.1007/978-1-4612-0783-2, ISBN 978-0-387-94370-1, MR 1321145 Deformations... homotopy type... Well, given a "well-behaved" family of quantum groups, which are deformations of the same group, is it "natural" to define this family as a homotopy type? Is HoTT, in some way, a natural setting to work with quantum groups because types and homotopy types are identified?
