Finite p-groups in which some subgroups are generated by elements of order p

Yakov Berkovich ; Department of Mathematics, University of Haifa, Haifa 31905, Israel

Sažetak

We prove that if a p-group G of exponent pe > p has no subgroup H such that |Ω1(H)| = pp and H/Ω1(H) is cyclic of order pe-1 ≥ p and H is regular provided e = 2, then G is either absolutely regular or of maximal class. This result supplements the fundamental theorem of Blackburn on p-groups without normal subgroups of order pp and exponent p. For p > 2, we deduce even stronger result than (respective result for p = 2 is unknown) a theorem of Bozikov and Janko.
