SUMMARY:Algebraic Graph Theory - Safet Penjić
CLASS:PUBLIC
DESCRIPTION:Summary \n\nTITLE: Short note about commutative association sch
 emes and specific\n(directed) family of graphs\n\nSPEAKER:\n Safet Penjić
 \n\nAFFILIATION:\n University of Primorska\n\nLOCATION:\n Please contact 
 Sabrina Lato for Zoom link\n\nABSTRACT: In this talk\, we consider the fo
 llowing problem:\n\n{\\bf Problem.} When the Bose--Mesner algebra ${\\cal
  M}$ of\ncommutative $d$-class association scheme ${\\mathfrak X}$ (which 
 is not\nnecessarily symmetric) can be generated by a $01$-matrix $A$? With
 \nother words\, for a given ${\\mathfrak X}$ can we find $01$-matrix $A$\n
 such that ${\\cal M}=(\\langle A\\rangle\, +\, \\cdot)$? \n
