Webb6 nov. 2024 · Simplicial resolutions can be constructed in various ways, for instance, by a comonad, or by a step-by-step method, developed by Michel André, that resembles the construction of a Eilenberg-Mac Lane space from a group presentation, followed by adding cells to ‘kill’ the higher homotopy groups. 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: included in disney plus
