Groups in Galway 2017
18-20 May, 2017
Groups in Galway has been running on an annual basis since 1978.
The scope of the conference covers all areas of group theory,
applications, and related fields.
ALL NUI Galway is committed to equality
of opportunity for all staff, students and visitors irrespective of
sex, marital status, family status, sexual orientation, religious
belief, age, disability, race, colour, nationality or ethnic or
national origin, membership of the travelling community or perceived
political belief or affiliation.
who are interested are invited to attend. There is no conference
fee. The web page of last year's Groups in Galway conference is

Generating sets of finite groups
It is well known that generating sets for groups are far more
complicated than generating sets for, say, vector spaces. The latter
satisfy the exchange axiom, and hence any two irredundant sets have
the same cardinality. According to the Burnside Basis Theorem, a
similar property holds for groups of prime power order.
We define a new sequence of relations on the elements of a finite
group, one for each positive integer r, where two elements of a finite
group are equivalent if each can be substituted for the other in any
r-element generating set. These relations become finer as r increases:
we define a new numerical group invariant to be the value of r at
which they stabilise. We are able to characterise this value of r for
all soluble groups, and give upper and lower bounds for all finite
groups.
The generating graph of a 2-generated finite group is a graph whose
vertices are the group elements, and whose edges are the 2-element
generating sets. Our new relations yield a precise description of the
automorphism group of the generating graph of any finite soluble group
with nonzero spread.

Two shall be the number of the counting
In ancient times, Brian Bowditch showed that if the boundary of a
one-ended hyperbolic group has a local cut point p, then p is
part of a cut pair, and the group virtually splits over virtually
Z.
We show that if the boundary of a one ended CAT(0) group G is
separated by a finite subset then it is separated by a cut pair, and G
virtually splits over virtually Z. We also examine nesting
actions on R-trees (because they wouldn't get out of the way).
