DESCRIPTION:Gromov's celebrated result says (colloquially) that one cannot
  symplectically embed a ball of radius 1.1 into a cylinder of radius 1. I 
 will show that in 4d if one removes from this ball a Lagrangian plane pass
 ing through the origin\, then such an embedding becomes possible. I will a
 lso show that this gives the smallest Minkowski dimension of a closed subs
 et with this property. I will end with many questions. This is based on jo
 int work with K. Sackel\, A. Song and J. Zhu.\n
