The stability and dynamics of almost strong zero $\ensuremath{\pi}$ modes in weakly nonintegrable Floquet spin chains are investigated. Such can also be viewed as localized Majorana at the edge a topological superconductor. Perturbation theory strength integrability breaking interaction ${J}_{z}$ is employed to estimate decay rates these modes, compared obtained from exact diagonalization. stru...

in the present paper, we rst modify the concepts of weakly fuzzy boundedness, strongly fuzzy boundedness, fuzzy continuity, strongly fuzzy continuity and weakly fuzzy continuity. then, we try to nd some relations by making a comparative study of the fuzzy norms of linear operators.

The aim of this paper is to introduce the concepts of fuzzy upper and fuzzy lower almost continuous, weakly continuous and almost weakly continuous multifunctions. Several characterizations and properties of these multifunctions along with their mutual relationships are established in $L$-fuzzy topological spaces

in this article we study two different generalizations of von neumann regularity, namely strong topological regularity and weak regularity, in the banach algebra context. we show that both are hereditary properties and under certain assumptions, weak regularity implies strong topological regularity. then we consider strong topological regularity of certain concrete algebras. moreover we obtain ...

In this paper, without assumption of monotonicity, we study the compactness and the connectedness of the weakly efficient solutions set to vector equilibrium problems by using scalarization method in locally convex spaces. Our results improve the corresponding results in [X. H. Gong, Connectedness of the solution sets and scalarization for vector equilibrium problems, J. Optim. Theory Appl. 133...

We present that there should exist a light strange-scalar meson κ, in addition to the κ(800), which has a mass around 1.1-1.2 GeV, a rather narrow width, and couples strongly to κ(800)σ(600) (Kπππ) but weakly to Kπ, based upon the Ũ(12)-classification scheme of hadrons and BES II data on J/ψ → K̄(892)Kπ decay.

2014 A strongly nonlinear, spatially invariant equation for the dynamics of a cellular flame is derived, on the assumption that the curvature of the flame front is small. The equation generalizes the corresponding weakly nonlinear equation, obtained previously near the stability threshold. J.

New types of systems of fuzzy relation inequalities and equations, called weakly linear, have been recently introduced in [J. Ignjatović, M. Ćirić, S. Bogdanović, On the greatest solutions to weakly linear systems of fuzzy relation inequalities and equations, Fuzzy Sets and Systems 161 (2010) 3081–3113.]. The mentioned paper dealt with homogeneous weakly linear systems, composed of fuzzy relati...

We show that for every separable Banach space X, either SPw(X) (the set of all spreading models of X generated by weakly-null sequences in X, modulo equivalence) is countable, or SPw(X) contains an antichain of the size of the continuum. This answers a question of S. J. Dilworth, E. Odell and B. Sari.
