TITLE: Nilpotent groups in which all proper subgroups
have "much" smaller class

 

ABSTRACT: Let G be a nilpotent group and suppose that G has distinct
maximal subgroups M and N of class at most n. Then Fitting’s theorem
implies that G has class at most 2n. It is known that if n ≥ 3 is a
positive integer and p is a prime with p ≥ 2n, then there exists a
finite p-group Hn of class 2n in which all maximal subgroups have
class at most n. Such groups Hn are necessarily 2-generator.

In this talk we'll consider some questions like the following: Let G
be a nilpotent group minimally generated by d elements and suppose
that all maximal subgroups of G have class at most n. What is the
largest possible class of G? (The results above give information about
the case d = 2) Our methods involve answering similar questions for
Lie algebras.
