SUMMARY:Learning seminar on Finite Relational Structures
CLASS:PUBLIC
DESCRIPTION:CARRIE KNOLL\, DEPARTMENT OF PURE MATHEMATICS\,  UNIVERSITY OF
  WATERLOO\n\n“IDEMPOTENT OPERATIONS IN REFLEXIVE DIGRAPHS”\n\nEvery pr
 ojection map is idempotent\, but the converse is not\nnecessarily true. In
  a general structure A\, it is possible that the\nonly binary idempotent o
 perations on A are the binary projection maps\,\nbut we can find a 3-ary i
 dempotent operation that is not a projection.\nThis cannot happen for fini
 te reflexive digraphs.
