WebbThe author gives a Yoneda-type interpretation of triple cohomology in a nonabelian setting. The impetus for this work comes from several sources, Eilenberg-MacLane cohomology of groups and its interpretations, the cohomology theory [bold]Ext[superscript italic]n for modules, and obstruction theory in topology. As the author states, the use of triples has …

WebbSimplicial Continuation, or Piecewise Linear Continuation (Allgower and Georg) is based on three basic results. The first is If F (x) maps IR^n into IR^ (n-1), there is a unique linear interpolant on an (n-1)-dimensional simplex which agrees with the function values at the vertices of the simplex. The second result is:
