Finite 2-groups with odd number of conjugacy classes

Andrei Jaikin-Zapirain, Joan Tent

In this paper we consider finite 2-groups with odd number of real conjugacy classes. On one hand we show that if $k$ is an odd natural number less than 24, then there are only fini…

Finite p-groups with small automorphism group

Jon Gonzalez-Sanchez, Andrei Jaikin-Zapirain

For each prime $p$ we construct a family ${G_{i}}$ of finite $p$ -groups such that $|\Aut (G_i)|/|G_i|$ goes to $0$ , as $i$ goes to infinity. This disproves a well-known conjecture…
