Remarks on microperiodic multifunctions
It is well known that a microperiodic function mapping a topological group into reals, which is continuous at some point is constant. We introduce the notion of a microperiodic multifunction, defined on a topological group with values in a metric space, and study regularity conditions implying an analogous result. We deal with Vietoris and Hausdorff continuity concepts.Stability of microperiodi...
متن کاملRemarks on Distance-Balanced Graphs
Distance-balanced graphs are introduced as graphs in which every edge uv has the following property: the number of vertices closer to u than to v is equal to the number of vertices closer to v than to u. Basic properties of these graphs are obtained. In this paper, we study the conditions under which some graph operations produce a distance-balanced graph.
متن کاملSome Remarks on Roeper’s Remarks on Chomsky’s ‘Remarks’
In his 1970 paper ‘Remarks on nominalization’, Noam Chomsky provided several arguments for the lexicalist hypothesis, namely the idea that nouns like refusal, rejection, growth, and so on are nouns throughout the entire syntactic derivation. Tom Roeper’s paper ‘Chomsky’s Remarks and the transformationalist hypothesis’ challenges the lexicalist hypothesis, arguing that such nouns are syntactical...
متن کاملRemarks on Modern Track Geometry Maintenance
A short survey on modern track maintenance methods is given, concentrating on the developments in recent years. The ongoing refinement of the machinery should be shown as the influence of IT-solutions. On top the economic view to the track infrastructure is briefly demonstrated. Further developments in track hardware solutions must respect the obtained high level of track work mechanization. H...
متن کاملUniversal Cupping Degrees
Cupping nonzero computably enumerable (c.e. for short) degrees to 0′ in various structures has been one of the most important topics in the development of classical computability theory. An incomplete c.e. degree a is cuppable if there is an incomplete c.e. degree b such that a∪b = 0′, and noncuppable if there is no such degree b. Sacks splitting theorem shows the existence of cuppable degrees....
