SUMMARY:Martin Bridson (Oxford University): Adventures in subdirect product
 s and residually free groups
DESCRIPTION:Martin Bridson: \nIn this talk\, which is for a wide audience\,
  I shall sketch the development of a body of ideas concerning the geometry
  and complexity of subgroups of direct products of groups\, which was deve
 loped in a long and joyful collaboration with Hamish Short\, Gilbert Baums
 lag\, Jim Howie and Chuck Miller\, starting in the 1990s. These ideas grea
 tly extended what is known about subgroups of direct products of hyperboli
 c groups\; they provided new tools for deciding which groups can be finite
 ly presented (the 1-2-3 Theorem and the VSP Theorem)\; and they led to a c
 omplete classification of finitely presented\, residually free groups. Gro
 ups will be the main objects of study\, but geometry is always close at ha
 nd.\n\n&nbsp\;\n\nMartin BRIDSON (Oxford university) - President of the C
