SUMMARY:Jérémy Alpacca (I2M): Coloring problems
DESCRIPTION:Jérémy Alpacca: Abstract : Who does not remember coloring as
  a child? It was a chance to let our imagination run free\, guided by a si
 ngle challenge: not to go outside the lines! Today\, we have grown up\, an
 d those days feel like a distant memory.\n\n\n\nIn this talk\, we will att
 empt to revive this childhood pastime from a mathematical perspective. How
 ever\, the goal is quite different. We want to determine the number of dis
 tinct colorings of an object made up of identical regions. At first glance
 \, this may seem like a purely combinatorial problem. Now\, if we color th
 e object and then manipulate it without altering its structure\, we still 
 obtain the same coloring. Group actions then become an essential tool for 
 counting these colorings. Concrete geometric examples will be explored to 
 highlight the connection with abstract algebra and to develop an intuitive
  understanding of the underlying concepts.\n\n
