چکیده
Let V be an r-dimensional $${\mathbb{F}_{{q^n}}}$$ -vector space. We call $${\mathbb{F}_{q}}$$ -subspace U of h-scattered if meets the h-dimensional -subspaces in dimension at most h. In 2000 Blokhuis and Lavrauw proved that $${\dim_{\mathbb{F}_{q}}}$$ ? rn/2 when is 1-scattered. Sub-spaces attaining this bound have been investigated intensively because their relations with projective two-weight codes strongly regular graphs. MRD-codes a maximum idealiser also linked to rn/2-dimensional 1-scattered subspaces n-dimensional (r ? 1)-scattered subspaces. paper we prove upper rn/(h + 1) for subspaces, h > 1, construct examples dimension. study intersection numbers hyperplanes, introduce duality relation among them, equivalence problem corresponding linear sets.

The Pe lczyński Property for Tight Subspaces
We show that if X is a tight subspace of C(K) then X has the Pe lczyński property and X is weakly sequentially complete. We apply this result to the space U of uniformly convergent Taylor series on the unit circle and using a minimal amount of Fourier theory prove that U has the Pe lczyński property and U is weakly sequentially complete. Using separate methods, we prove U and U have the Dunford...
متن کاملPositive Bases in Ordered Subspaces with the Riesz Decomposition Property
In this article we suppose that E is an ordered Banach space the positive cone of which is defined by a countable familyF={fi|i ∈ N} of positive continuous linear functionals of E, i.e. E+ = {x ∈ E | fi(x) ≥ 0, for each i} and we study the existence of positive (Schauder) bases in the ordered subspaces X of E with the Riesz decomposition property. So we consider the elements x of E as sequences...
متن کاملRigorous Restricted Isometry Property of Low-Dimensional Subspaces
Dimensionality reduction is in demand to reduce the complexity of solving largescale problems with data lying in latent low-dimensional structures in machine learning and computer version. Motivated by such need, in this work we study the Restricted Isometry Property (RIP) of Gaussian random projections for low-dimensional subspaces in R , and rigorously prove that the projection Frobenius norm...
متن کاملGeneralising Conservativity
A constraint on functions from sets and relations to sets is studied. This constraint is a generalisation of the constraint of conservativity known from the study of generalised quantifiers in natural languages. It is suggested that this generalised constraint constitutes a semantic universal.
متن کاملBishop ’ S Property ( Β ) , Hypercyclicity and Hyperinvariant Subspaces
The question whether every operator on H has an hyperinvariant subspace is one of the most difficult problems in operator theory. The purpose of this paper is to make a beginning on the hyperinvariant subspace problems for another class of operators closely related to the normal operators namely, the class of k -quasi-class A operators. A necessary and sufficient condition for the hypercyclicit...
