SUMMARY:Algebraic Combinatorics - Sergey Yurkevich
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Algebraicity of solutions of functional equ
 ations with one\ncatalytic variable\n\nSpeaker:\n Sergey Yurkevich\n\nAffi
 liation:\n University Paris-Saclay\n\nLocation:\n MC 5479 or contact Olya
  Mandelshtam for Zoom link\n\nABSTRACT: Abstract: Numerous combinatorial
  enumeration problems\nreduce to the study of functional equations which c
 an be solved by a\nuniform method introduced by Bousquet-Mélou and Jehann
 e in 2006. In\nmy talk\, I will first briefly explain this result and its 
 proof. Then\nI will present a new generalization of it to the case of syst
 ems of\nfunctional equations with one catalytic variable. The method is\nc
 onstructive and yields an algorithm for computing the minimal\npolynomials
  of interest.\n
