On the Reflexivity of Contractions on Hilbert Space
Let T be a bounded operator on the Hilbert space Jf. We denote by W{T) the weakly closed algebra generated by T and / and, as usual, we denote by Alg Lat(T') the set of those operators X with the property that XM c M whenever M is an invariant subspace for T. Of course, we always have W{T) <= Alg Lat(r), and T is said to be reflexive if W{T) = Alg Lat(7). The letter S will always stand for the ...
متن کاملSpace versus Time: Unimodular versus Non-Unimodular Projective Ring Geometries?
Finite projective (lattice) geometries defined over rings instead of fields have recently been recognized to be of great importance for quantum information theory. We believe that there is much more potential hidden in these geometries to be unleashed for physics. There exist specific rings over which the projective spaces feature two principally distinct kinds of basic constituents (points and...
متن کاملOrthogonal metric space and convex contractions
In this paper, generalized convex contractions on orthogonal metric spaces are stablished in whath might be called their definitive versions. Also, we show that there are examples which show that our main theorems are genuine generalizations of Theorem 3.1 and 3.2 of [M.A. Miandaragh, M. Postolache and S. Rezapour, {it Approximate fixed points of generalized convex contractions}, Fixed Poi...
متن کاملViscosity approximation methods for W-mappings in Hilbert space
We suggest a explicit viscosity iterative algorithm for nding a common elementof the set of common xed points for W-mappings which solves somevariational inequality. Also, we prove a strong convergence theorem with somecontrol conditions. Finally, we apply our results to solve the equilibrium problems.Finally, examples and numerical results are also given.
متن کاملLinking in Hilbert Space
We present the most general definition of the linking of sets in a Hilbert space and, drawing on the theory given in [ST, T, Sc3], give a necessary and sufficient geometric condition for linking when one set is compact.
