Weak Banach-Saks property in the space of compact operators
For suitable Banach spaces $X$ and $Y$ with Schauder decompositions and a suitable closed subspace $mathcal{M}$ of some compact operator space from $X$ to $Y$, it is shown that the strong Banach-Saks-ness of all evaluation operators on ${mathcal M}$ is a sufficient condition for the weak Banach-Saks property of ${mathcal M}$, where for each $xin X$ and $y^*in Y^*$, the evaluation op...
متن کاملProperty of σ(600) and Chiral Symmetry
The chiral symmetry and the notion of its dynamical breaking have been playing a central role in understanding the spectroscopy of hadrons with light-quarks. Presently the non-linear representation (Non-Linear σ Model(NLσM)) of chiral SU(2)L×SU(2)R group is widely accepted to be realized in nature on the basis of the success of low energy theorems concerning π mesons as Nambu-Goldstone bosons. ...
متن کاملOre Extensions over Weak Σ - Rigid Rings
Let R be a ring, σ an automorphism of R and δ a σ-derivation of R. We recall that a ring R is said to be a δ-ring if aδ(a) ∈ P (R) implies a ∈ P (R), where P (R) denotes the prime radical of R. It is known that, if R is a Noetherian ring, σ an automorphism of R such that aσ(a) ∈ P (R) implies a ∈ P (R) and δ a σ-derivation of R such that R is a δ-ring with σ(δ(a)) = δ(σ(a)), for all a ∈ R, then...
متن کاملThe Weak Repulsion Property
In 1926 M. Lavrentiev [7] proposed an example of a variational problem whose infimum over the Sobolev spaceW, for some values of p ≥ 1, is strictly lower than the infimum overW1,∞. This energy gap is known since then as the Lavrentiev phenomenon. The aim of this paper is to provide a deeper insight into this phenomenon by shedding light on an unnoticed feature. Any energy that presents the Lavr...
متن کاملWeak Σ-distributivity of Lattice Ordered Groups
In this paper we prove that the collection of all weakly distributive lattice ordered groups is a radical class and that it fails to be a torsion class.
