DESCRIPTION:Title: No growth-gaps for special cube complexes I.\n\n \n\nAbs
 tract: This will consist of two lectures\, the first by Wise and the secon
 d by Li on their joint work.  Let be G the fundamental group of a compact 
 special cube complex. We show that there is a sequence of infinite index q
 uasiconvex subgroups whose growth-rates converge to the growth-rate of G.
 \n\nIn the first talk\, we will discuss growth-rates\, prove the result in
  the case when G is a free group (work of Dahmani-Futer-Wise)\, sketch a p
 roof of the general case. In the second talk\, we will give details of the
  proof\, including the automatic structure that it relies upon and the met
 hod for using automata to estimate growth-rates. We will also survey a col
 lection of problems that are motivated by this work.\n\n \n
