Bounding the exponent of a finite group by the exponent of the automorphism group and a theorem of Schur
P. Komma, V. Z. Thomas
Assume is a finite -group, and let be a Sylow -subgroup of with . We prove that if is of class , then $\exp(G)|p^{\ceil{\log…

Non-inner automorphisms of order p in finite p-groups of coclass 4 and coclass 5
P. Komma
A long-standing conjecture asserts that every finite nonabelian -group has a non-inner automorphism of order . In this paper we prove the conjecture for finite -groups of…

A note on non-inner automorphism conjecture
P. Komma
In this paper we prove that every -generator finite -group has a non-inner automorphism of order leaving elementwise fixed (). Moreover, we prove…

A lemma on the exponent of Schur multiplier of groups with good power structure
A. E Antony, P. Komma, V. Z. Thomas
In this note, we give short proofs of the well-known results that the exponent of the Schur multiplier $\M$ divides the exponent of $\G$ for finite $\p$-groups of maximal class and…
