SUMMARY:Shuffle operads - Dotsenko\, V (Trinity College Dublin)

DESCRIPTION:Symmetric operads\, usually arising in applications\, provide 
 a language to work with algebraic properties exhibited by substitutions of
  operations with many arguments into one another. Because of multiple argu
 ments of operations\, one naturally has symmetries (permutations of argume
 nts of an operation) present in all arising questions. Contrary to what th
 ey teach us\, in many of these questions symmetries rather get in the way 
 than are helpful. A way to make symmetries almost disappear is to move to 
 a large universe of "shuffle operads". Shuffle operads are easier to handl
 e\, and answers to many questions on symmetric operads can be derived from
  the respective answers in the shuffle world. The goal of this talk is to 
 give an introduction to this circle of questions for beginners\, and to ou
 tline some applications.\n
