Abstract: The notion of inner linear Hopf algebra is a generalization of the notion ofdiscrete linear group. In this paper, we prove two general results that enableus to enlarge the class of Hopf algebras that are known to be inner linear: thefirst one is a characterization by using the Hopf dual, while the second one isa stability result under extensions. We also discuss the related notion ofinner unitary Hopf *-algebra.
