NOTE this is a THURSDAY and starting time has been moved up to 1 PM or a bit later if anyone can't make it right at 1PM



We discuss the deformed function bialgebra of a simply connected reductive Lie group using a basis consisting of matrix elements of finite dimensional representations. This leads to a preferred presentation of the deformation in that basis, meaning one where the structure constants of comultiplication are unchanged on all elements. The structure constants of multiplication are controlled by quantum 3j-Symbols.
