FROM COMPACT QUANTUM GROUPS TO MULTIPLIER HOPF ALGEBRAS:
the Peter-Weyl theory of compact quantum groups (existence of the Haar
measure, dense *-Hopf subalgebras, representation theory),
universal compact quantum groups and free products
of compact quantum groups (Banica and Wang),
Rieffel's deformations (quantizations) of Lie groups,
C*-algebraic quantum groups from multiplier Hopf algebras
