SUMMARY:Algebraic Graph Theory - Safet Penjić
CLASS:PUBLIC
DESCRIPTION:TITLE: Short note about commutative association schemes and spe
 cific\n(directed) family of graphs\n\nSPEAKER:\n Safet Penjić\n\nAFFILIAT
 ION:\n University of Primorska\n\nLOCATION:\n Please contact Sabrina Lato
  for Zoom link\n\nABSTRACT: In this talk\, we consider the following prob
 lem:\n\n{\\bf Problem.} When the Bose--Mesner algebra ${\\cal M}$ of\ncom
 mutative $d$-class association scheme ${\\mathfrak X}$ (which is not\nnece
 ssarily symmetric) can be generated by a $01$-matrix $A$? With\nother word
 s\, for a given ${\\mathfrak X}$ can we find $01$-matrix $A$\nsuch that ${
 \\cal M}=(\\langle A\\rangle\, +\, \\cdot)$?
