Călinescu, Corina On the bijectivity of the antipode in a co-Frobenius Hopf algebra. (English) Zbl 1049.16021 Bull. Math. Soc. Sci. Math. Roum., Nouv. Sér. 44(92), No. 1, 59-62 (2001). Summary: We give a simplification for the proof of the bijectivity of the antipode in a co-Frobenius Hopf algebra, a result due to D. E. Radford [J. Algebra 46, 189-195 (1977; Zbl 0361.16002)].
