Hyperspace selections avoiding points

چکیده
We deal with a hyperspace selection problem in the setting of connected spaces. present two solutions this illustrating difference between selections for nonempty closed sets, and those at most two-point sets. In first case, we obtain characterisation compact orderable latter case --- that same property is equivalent to existence ternary relation on space, known as cyclic order, gives so called weakly cyclically

Fixed points avoiding Abelian k-powers
We show that the problem of whether the fixed point of a morphism avoids Abelian k-powers is decidable under rather general conditions.
متن کاملQuasicrystals: sections of hyperspace.
It was, and still is, a fundamental law of crystallography that fivefold rotational symmetry and three-dimensional (3D) lattice periodicity are mutually incompatible. With this in mind, the Israeli materials scientist Dan Shechtman did not trust his eyes when he inspected electron diffractograms of rapidly solidified Al-Mn. What he expected to see was either diffraction patterns with sharp Brag...

It was not until the sixteenth century that dead bodies were submitted to medico-legal investigation. The horror which human dissections inspired in the ancients, and the religious awe with which they beheld the mortal wreck of their fellows, not only retarded the progress of anatomy and physiology, but excluded the light of medicine from the researches of the forum. The Jewish law, indeed, con...
متن کاملChaos on Hyperspace
In this paper, the chaotic behavior of a set-valued mapping F : X → 2 , where X is a compact space, is investigated. The existence of the generalized shadowing property in the hyperspace 2 is proved. Based on the generalized shadowing property of the set-valued mappings F and the assumption of the existence of an unstable chain recurrent point of the mapping F , it is shown that the Bernoulli s...
متن کاملIntelligent Mapping of Hyperspace
This paper addresses some particular issues related to the difficult task of automatically structuring information available in ill-structured environments, through a distributed hypermedia system like the Web. We present an original approach to this problem, which coordinates different aspects of automatic computation of relations between nodes in hyperspace, through dynamic linking, using int...
