SUMMARY:Universal Algebra Learning Seminar
CLASS:PUBLIC
DESCRIPTION:ROSS WILLARD\, DEPARTMENT OF PURE MATHEMATICS\, UNIVERSITY OF W
 ATERLOO\n\n\"Dualizing the finite level\"\n\nLast week\, Justin proved the
  Duality Compactness Theorem\, which\nreduces the task of proving a dualit
 y to proving it “at the finite\nlevel\,” that is\, for the finite alge
 bras in the quasi-variety\nISP(M)\, at least for alter egos with a finite 
 signature. This week I\nwill present a characterization of when an alter e
 go dualizes the\nfinite algebras in ISP(M). The characterization is especi
 ally useful\nwhen the term operations of M are understood.\n\nMC 5403
