Metric Semigroups and Groups of Multisets

open access: yesResearches in Mathematics
We investigate the algebraic and topological properties of sets of complex multisets associated with Banach spaces having symmetric bases. We consider algebraic structures on the sets of multisets and compare some natural metrics on the (semi)groups of ...

Dynamics of multivalued linear operators

open access: yesOpen Mathematics, 2017
We introduce several notions of linear dynamics for multivalued linear operators (MLO’s) between separable Fréchet spaces, such as hypercyclicity, topological transitivity, topologically mixing property, and Devaney chaos.

Contralesional Sensorimotor Network Participates in Motor Functional Compensation in Glioma Patients

open access: yesFrontiers in Oncology, 2022
BackgroundSome gliomas in sensorimotor areas induce motor deficits, while some do not. Cortical destruction and reorganization contribute to this phenomenon, but detailed reasons remain unclear.

What is Topological about Topological Dynamics? [PDF]

open access: yes, 2018
We consider various notions from the theory of dynamical systems from a topological point of view.Many of these notions can be sensibly defined either in terms of (finite) open covers or uniformities.

Weak Darboux property and transitivity of linear mappings on topological vector spaces

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2013
It is shown that every linear mapping ontopological vector spaces always has weak Darboux property, therefore, it is continuous ifand only if it is transitive.

Topological origin of the protein folding transition

open access: yesPhysical Review E, 2022
In this paper, a geometrical and thermodynamical analysis of the global properties of the potential energy landscape of a minimalistic model of a polypeptide is presented. The global geometry of the potential energy landscape is supposed to contain relevant information about the properties of a given sequence of amino acids, that is, to discriminate ...

Topological transitivity of compact actions on 𝐶*-algebras

open access: yes, 1990
We give some conditions under which minimality is equivalent to the other notions in noncommutative ergodic theory and prove that in a compact C ∗ {{\mathbf {C}}^

A Coarse Geometric Approach to Graph Layout Problems

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT We define a range of new coarse geometric invariants based on various graph–theoretic measures of complexity for finite graphs, including treewidth, pathwidth, cutwidth and bandwidth. We prove that, for bounded degree graphs, these invariants can be used to define functions which satisfy a strong monotonicity property, namely, they are ...
