A Note on Barnette’s Conjecture

open access: yesDiscussiones Mathematicae Graph Theory, 2013
Barnette conjectured that each planar, bipartite, cubic, and 3-connected graph is hamiltonian. We prove that this conjecture is equivalent to the statement that there is a constant c > 0 such that each graph G of this class contains a path on at least c ...

Feebly Limit Sets and Cartan G – space

open access: yesJournal of Kufa for Mathematics and Computer, 2011
The main goal of this work is to create a general type of G – space , namely, feebly Cartan G – space and a new type of limit sets , namely, feebly limit sets  ,and, give some properties and some equivalent statement of these concept also we ...

Topological operators and completeness of spectrum in discrete gauge theories

open access: yesJournal of High Energy Physics, 2020
In many gauge theories, the existence of particles in every representation of the gauge group (also known as completeness of the spectrum) is equivalent to the absence of one-form global symmetries.

Equivalent Statements of Two Multidimensional Hilbert-Type Integral Inequalities with Parameters

open access: yesAxioms, 2023
By means of the weight functions, the idea of introduced parameters and the transfer formulas, two multidimensional Hilbert-type integral inequalities with the general nonhomogeneous kernel as H(||x||αλ1||y||βλ2)(λ1,λ2≠0) are given, which are some extensions of the Hilbert-type integral inequalities in the two-dimensional case.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Short Proofs for Slow Consistency

open access: yes, 2020
Let $\operatorname{Con}(\mathbf T)\!\restriction\!x$ denote the finite consistency statement "there are no proofs of contradiction in $\mathbf T$ with $\leq x$ symbols".

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Separation properties of the Wallman ordered compactification

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1990
The Wallman ordered compactification ω0X of a topological ordered space X is T2-ordered (and hence equivalent to the Stone-Čech ordered compactification) iff X is a T4-ordered c-space.

Equivalence of large-N gauge theories on a group manifold and its coset space

open access: yesPhysics Letters B, 2018
In 2010, Kawai, Shimasaki and one of the present authors (A.T.) showed that the large-N reduction holds on group manifolds in the sense that a large-N gauge theory on a group manifold is realized by a matrix model which is obtained by dimensionally ...

Homotopy equivalence of nearby Lagrangians and the Serre spectral sequence

open access: yes, 2016
We construct using relatively basic techniques a spectral sequence for exact Lagrangians in cotangent bundles similar to the one constructed by Fukaya, Seidel, and Smith.
