SUMMARY:Graphs and Matroids Seminar - Alvaro Carbonero Gonzales
CLASS:PUBLIC
DESCRIPTION:TITLE: An into introduction to the chromatic number of digraph\
 n\nSpeaker:\n Alvaro Carbonero Gonzales\n\nAffiliation:\n University of Wa
 terloo\n\nRoom:\n MC 5417\, please contact Shalya Redlin for zoom link\n\n
 ABSTRACT: A proper $k$-coloring of a digraph $D$ is a coloring of the\nver
 tices such that every color class is acyclic\, and the dichromatic\nnumber
  of a digraph $D$ is the minimum number $k$ such that there is a\nproper $
 k$-coloring of $D$. Many questions about the chromatic number\ncan be aske
 d about the dichromatic number\, but as one will quickly\nobserve\, unsusp
 ected complications arise when dealing with digraphs.
