SUMMARY:Stability in permutations - Goulnara Arzhantseva (University of Vi
 enna)

DESCRIPTION:An equation is stable if an almost-solution (or a solution of 
 the corresponding inequality) is close to an exact solution. For example\,
  xyx^-1y^-1=1 is stable if almost commuting matrices are\, in the given no
 rm and independently of the matrix size\, close to matrices that commute. 
 Over the past few years\, the topic has flourished rapidly\, expanding in 
 many exciting directions. Focusing on permutation matrices\, we give an in
 troduction to the topic\, outline recent developments\, and suggest a few 
 open problems.\n&nbsp\;\nBased on joint works with Liviu Paunescu (Buchare
 st).
