Khalil MINIMAL PROJECTIONS IN TENSOR PRODUCT SPACES
It is the object of this paper to study the existence and the form of minimal projections in some spaces of tensor products of Banach spaces. We answer a question of Franchetti and Cheney for finitely codimensional subspaces in C(K ) [1].
متن کاملMinimal 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 کاملWOVEN FRAMES IN TENSOR PRODUCT OF HILBERT SPACES
The tensor product is the fundemental ingredient for extending one-dimensional techniques of filtering and compression in signal preprocessing to higher dimensions. Woven frames play a crucial role in signal preprocessing and distributed data processing. Motivated by these facts, we have investigated the tensor product of woven frames and presented some of their properties. Besides...
