Minimal Shape-preserving Projections onto N
In this paper are determined minimal shape-preserving projections onto the n-th degree algebraic polynomials.
متن کاملThe Geometry of Minimal Shape-preserving Projections onto N
We obtain minimal shape-preserving projections onto the n-th degree algebraic polynomials via a geometric approach.
متن کاملMinimal Shape-preserving Projections Onto Πn: Generalizations and Extensions
The goal of this paper is to further the investigation begun in [6]. With the benefit of nearly ten years of work, we begin by indicating how several proofs from [6] can be substantially improved. We show that the problem of preserving k-convexity onto Πn is one part of a larger shape-preserving problem (multi-convex preservation) relative to Πn and we completely solve this expanded problem. An...
متن کاملUniqueness of Minimal Projections onto Two-dimensional Subspaces
In this paper we prove that the minimal projections from Lp (1 < p < ∞) onto any two-dimensional subspace is unique. This result complements the theorems of W. Odyniec ([OL, Theorem I.1.3], [O3]) We also investigate the minimal number of norming points for such projections.
متن کاملExact Projections onto the Hemisphere
Recent approaches to realistic image synthesis have split the rendering process into two passes. The first pass calculates an approximate global illumination solution, the second generates an image of high quality from a given view point using the illumination solution obtained in the first pass. This paper discusses a new method for projecting polygons onto the hemisphere which is the central ...
