abstract:assume that y is a banach space such that r(y ) ? 2, where r(.) is garc?a-falset’s coefficient. and x is a banach space which can be continuously embedded in y . we prove that x can be renormed to satisfy the weak fixed point property (w-fpp). on the other hand, assume that k is a scattered compact topological space such that k(!) = ? ; and c(k) is the space of all real continuous ...
This article concerns over-resolution methods for image reconstruction from data provided by a family of scanning instruments like the Herschel observatory. The work is centered on building a model of the instrument that faithfully reflects the physical reality, accurately taking the acquisition process into account so as to explain the data in a reliable manner. The inversion, i.e. the image r...
We present a status report of dedicated circular polarization (CP) global VLBI observations of SS433. The total intensity image of the source is presented. We do not detect linear polarization in the core region of the source. We estimate the errors in D-terms for the EVN, and its effect on the final right-left circular polarization gain calibration. The data from this and earlier observations ...
In this note, we present the hyperbolic Menelaus theorem in the Poincaré disc of hyperbolic geometry. 2000 Mathematical Subject Classi cation: 30F45, 20N99, 51B10, 51M10 Keywords and phrases: hyperbolic geometry, hyperbolic triangle, gyrovector 1. Introduction Hyperbolic Geometry appeared in the rst half of the 19 century as an attempt to understand Euclids axiomatic basis of Geometry. It is ...
Graph neural network (GNN) has shown superior performance in dealing with structured graphs, which attracted considerable research attention recently. Most of the existing GNNs are designed Euclidean spaces; however, real-world spatial data can be non-Euclidean surfaces (e.g., hyperbolic spaces). For example, biologists may inspect geometric shape a protein surface to determine its interaction ...
the space now known as complete erdos space ec was introduced by paul erdos in 1940 as the closed subspace of the hilbert space ?2 consisting of all vectors such that every coordinate is in the convergent sequence {0} ? { 1 n : n ? n}. in a solution to a problem posed by lex g. oversteegen we present simple and useful topological characterizations of ec. as an application we determine the ...
in chapter 1, charactrizations of fragmentability, which are obtained by namioka (37), ribarska (45) and kenderov-moors (32), are given. also the connection between fragmentability and its variants and other topics in banach spaces such as analytic space, the radone-nikodym property, differentiability of convex functions, kadec renorming are discussed. in chapter 2, we use game characterization...
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
We describe the dynamics of magnetic skyrmions in synthetic antiferromagnets (SAF), with a finite interlayer coupling. Due to opposite gyrovector two SAF layers, coupled reach stationary regime spatial separation, direction orthogonal their velocity. As consequence, and contrary ferromagnetic situation, transient necessarily occurs, acceleration, related an inertia, that limits its time respons...
