SUMMARY:Algebraic and Enumerative combinatorics seminar -Scott\nNeville-Eve
 ntual sign coherence
CLASS:PUBLIC
DESCRIPTION:SPEAKER:\n Scott Neville\n\nAFFILIATION:\n LACIM\n\nLOCATION:\n
  MC 6460\n\nABSTRACT: The sign coherence of c-vectors is one of the funda
 mental\ntheorems of cluster algebras with principal coefficients.  Gekhtm
 an\nand Nakanishi posed the Asymptotic Sign Coherence Conjecture for\nclus
 ter algebras with arbitrary coefficients\, which says sign\ncoherence shou
 ld eventually hold in any sufficiently generic infinite\nmutation sequence
 .  We prove that for cluster algebras from quivers\nof arbitrary rank\, t
 heir conjecture holds with probability 1 for a\nrandom mutation sequence.
   Our results also establish the conjecture\nin full generality for many 
 families of quivers.  This is joint work\nwith Amanda Burcroff.\n\nTHERE 
 WILL BE A PRE-SEMINAR PRESENTING RELEVANT BACKGROUND AT\nBEGINNING GRADUAT
 E LEVEL STARTING AT 1:30PM IN MC 5417.
