DESCRIPTION:Perla Sousi (Cambridge) will speak in the Probability seminar
 . \n\nA uniform spanning tree of Z^4 can be thought of as the ‘’uniform 
 \nmeasure’’ on trees  of Z^4. The past of 0 in the uniform spanning tree
  \nis the finite component that is disconnected from infinity when 0 is 
 \ndeleted from the tree. We establish the logarithmic corrections to the
  \nprobabilities that the past contains a path of length n\, that it has
  \nvolume at least n and that it reaches the boundary of the box of side
  \nlength n around 0. Dimension 4 is the upper critical dimension for th
 is \nmodel in the sense that in higher dimensions it exhibits "mean-fiel
 d" \ncritical behaviour. An important part of our proof is the study of 
 the \nNewtonian capacity of a loop erased random walk in 4 dimensions. T
 his is \njoint work with Tom Hutchcroft.
