Topological Lifshitz transitions [PDF]

open access: yesLow Temperature Physics, 2017
Different types of Lifshitz transitions are governed by topology in momentum space. They involve the topological transitions with the change of topology of Fermi surfaces, Weyl and Dirac points, nodal lines, and also the transitions between the fully gapped states.

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.

Loss-Driven Topological Transitions in Lasing

open access: yesPhysical Review Letters, 2022
We experimentally observe lasing in a hexamer plasmonic lattice and find that when tuning the scale of the unit cell, the polarization winding of the emission changes. By a theoretical analysis we identify the lasing modes as quasi bound states in continuum (quasi-BICs) of topological charges of zero, one or two.

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.

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.

Topological Connectedness and Behavioral Assumptions on Preferences: A Two-Way Relationship

open access: yes, 2018
This paper offers a comprehensive treatment of the question as to whether a binary relation can be consistent (transitive) without being decisive (complete), or decisive without being consistent, or simultaneously inconsistent or indecisive, in the ...

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 ...

On homeomorphisms with the two-sided limit shadowing property

open access: yes, 2014
We prove that the two-sided limit shadowing property is among the strongest known notions of pseudo-orbit tracing. It implies shadowing, average shadowing, asymptotic average shadowing and specification properties.

Topology and Phase Transitions: Paradigmatic Evidence [PDF]

open access: yesPhysical Review Letters, 2000
We report upon the numerical computation of the Euler characteristic (a topologic invariant) of the equipotential hypersurfaces _v of the configuration space of the two-dimensional lattice $ ^4$ model. The pattern ( _v) vs. v (potential energy) reveals that a major topology change in the family { _v}_{v\in R} is at the origin of the phase ...
