Interpolation and Approximation from Convex Sets
Let X be a topological vector space, Y = IR n , n 2 IN, A a continuous linear map from X to Y , C X, B a convex set dense in C, and d 2 Y a data point. We derive conditions which guarantee that the set B \ A ?1 (d) is nonempty and dense in C \ A ?1 (d). Some applications to shape preserving interpolation and approximation are described.
متن کاملInterpolation and Approximation from Convex Sets II. In nite-Dimensional Interpolation
Let X and Y be topological vector spaces, A be a continuous linear map from X to Y , C X, B be a convex set dense in C, and d 2 Y be a data point. Conditions are derived guaranteeing the set B \ A ?1 (d) to be nonempty and dense in C \ A ?1 (d). The paper generalizes earlier results by the authors to the case where Y is innnite dimensional. The theory is illustrated with two examples concerning...
متن کاملBlind approximation of planar convex sets
The process of learning the shape of an unknown convex planar object through an adaptive process of simple measurements called Line probings, which reveal tangent lines to the object, is considered. A systematic probing strategy is suggested and an upper bound on the number of probings it requires for achieving an approximation with a pre-specified precision to the unknown object is derived. A ...
متن کاملSpline interpolation between hyperspaces of convex or fuzzy sets
We consider the interpolation problem for functions whose range and whose domain both consist of convex or fuzzy subsets of a real Euclidean space. This problem arises in fuzzy controlling, namely when the functional dependence between two fuzzy vectors is known only for finitely many cases. To have a criterion for an appropriate choice of an interpolation function, we generalise the well-known...
متن کاملApproximation and the Topology of Rationally Convex Sets
Considering a mapping g holomorphic on a neighbourhood of a rational convex set K ⊂ C, and range into the complex projective space CP, the main objective of this paper is to show that we can uniformly approximate g on K by rational mappings defined from C into CP. We only need to ask that the second Čech cohomology group Ȟ(K, Z) vanishes.
