SUMMARY:Algebraic Graph Theory Seminar - Hamed Karami
CLASS:PUBLIC
DESCRIPTION:TITLE: Perfect Colorings of the Generalized Petersen Graphs\n\
 nSpeaker:\n Hamed Karami\n\nAffiliation:\n Iran University of Science and 
 Technology\n\nZoom:\n Contact Soffia Arnadottir\n\nABSTRACT:\n\nFor a grap
 h G and an integer m\, a mapping T:V(G) -> {1\,...\,m} is\ncalled a perfec
 t m-coloring with matrix A=(a_ij)\, i\,j \\in {1\,...\,m}\,\nif it is surj
 ective\, and for all i\,j\, for every vertex of color i\, the\nnumber of i
 ts neighbors of color j is equal to a_ij. There is another\nterm for this 
 concept in literature as \"equitable partition\". In this\ntalk\, we prese
 nt some important results about enumerating parameter\nmatrices of all per
 fect 2-colorings and perfect 3-colorings of\ngeneralized Petersen graphs G
 P(n\,k).
