Minimal Non-fc-groups And Coprime Automorphisms Of Quasi-simple Group

A group G is called an FC-group if the conjugacy class of every
element is finite. G is called a minimal non-FC-group if G is
not an FC-group, but every proper subgroup of G is an FC-group.
The first part of this thesis is on minimal non-FC-groups and
their finitary permutational representations. Belyaev proved in
1998 that, every perfect locally finite minimal non-FC-group has
non-trivial finitary permutational representation. In Chapter 3,
we write the proof of Belyaev in detail.

Recall that a group G is called quasi-simple if G is perfect
and G/Z(G) is simple. The second part of this thesis is on
finite quasi-simple groups and their coprime automorphisms. In
Chapter 4, the result of Parker and Quick is written in detail:
Namely / if Q is a quasi-simple group and A is a non-trivial
group of coprime automorphisms of Q satisfying |Q: C_{Q}(A)| &lt / n then |Q| &lt / n3,
that is |Q| is bounded by a function of n.
