SOME PROPERTIES OF PREREFLEXlVE SUBSPACES OF OPERATORS

In the paper, we define a notion of prereflexivity for subspaces, give several equivalent conditions of this notion and prove that if $ C_ L(H) is prereflexive, then every aweakly closed subspace of S is prereflexive if and only if $ has the property WP(see definition 2.11). By our result, we construct a reflexive operator A such that A 0 is not prereflexive.

Ela Some Subspaces of the Projective Space

Let V be a 2m-dimensional vector space over a field F (m ≥ 2) and let k ∈ {1, . . . , 2m − 1}. Let A2m−1,k denote the Grassmannian of the (k − 1)-dimensional subspaces of PG(V ) and let egr denote the Grassmann embedding of A2m−1,k into PG( ∧k V ). Let S be a regular spread of PG(V ) and let XS denote the set of all (k − 1)-dimensional subspaces of PG(V ) which contain at least one line of S. T...

Some Properties of C-frames of Subspaces

In [13] frames of subspaces extended to continuous version namely c-frame of subspaces. In this article we consider to the relations between cframes of subspaces and local c-frames. Also in this article we give some important relation about duality and parseval c-frames of subspaces.

Some Effective Oop Examples

This paper will present two examples that we feel can convince students of the benefits of object-oriented design and spur their interest. Both examples are well-known and fun to program. We first describe a sorting animation. In this project we will ask students to implement animation of various sorting algorithms, and for each sorting algorithm the user can choose one of two methods of animat...
