Webb6 dec. 2024 · Given a space and an open cover, the nerve of the cover is a simplicial complex (see Čech methods and the discussion there). The Vietoris complex is another given by a related method. Given any two sets X X and Y Y , and a relation R ⊆ X × Y R\subseteq X\times Y , there are two simplicial complexes that encode information on … WebbThis paper presents a digest of recently developed simplicial and continuation methods for approximating fixed-points or zero-points of nonlinear finite-dimensional mappings. Underlying the methods are algorithms for following curves which are implicitly defined, as for example, in the case of homotopies. The details of several algorithms are outlined …

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.
