DESCRIPTION:An ALC (asymptotically locally conical) manifold i
 s a complete non-compact&nbsp\;Riemannian manifold
  whose ends are modelled on circle fibrations over
  Riemannian cones of one lower dimension with fibr
 es of asymptotically constant finite length. In di
 mension 4 and when the asymptotic cone is flat the
  acronym ALF (asymptotically locally flat) is more
  commonly used.&nbsp\;(Conjectural) examples of AL
 C manifolds with G2 holonomy have appeared both in
  the physics and mathematics literature since the 
 early 2000&rsquo\;s. ALC G2 manifolds provide inte
 resting models for understanding how&nbsp\;compact
  G2 manifolds can collapse to Calabi-Yau 3-folds. 
  In this talk I will discuss the construction of v
 arious families of ALC G2 manifolds and describe t
 heir geometric properties. This is joint work with
  Mark Haskins (Imperial College London) and Johann
 es Nordstr&ouml\;m (University of Bath).
