Equivariant toric geometry and Euler–Maclaurin formulae

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract We first investigate torus‐equivariant motivic characteristic classes of toric varieties, and then apply them via the equivariant Riemann–Roch formalism to prove very general Euler–Maclaurin‐type formulae for full‐dimensional simple lattice polytopes.

Commutators in real interpolation with quasi-power parameters

open access: yesAbstract and Applied Analysis, 2002
The basic higher order commutator theorem is formulated for the real interpolation methods associated with the quasi-power parameters, that is, the function spaces on which Hardy inequalities are valid.

Ghost effect from Boltzmann theory

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract Taking place naturally in a gas subject to a given wall temperature distribution, the “ghost effect” exhibits a rare kinetic effect beyond the prediction of classical fluid theory and Fourier law in such a classical problem in physics. As the Knudsen number ε$\varepsilon$ goes to zero, the finite variation of temperature in the bulk is ...

Unimodular Commutators [PDF]

open access: yesProceedings of the American Mathematical Society, 1987
Let R R be a principal ideal ring and M k , n {M_{k,n}} the set of k × n k \times n matrices over R R . The following statments are proved: (a) If k ≤ n

Ultra High Step‐Up Soft Switching Converter Based on the Interleaved Structure

open access: yesEnergy Science &Engineering, EarlyView.
The proposed topology provides high voltage gain and enhanced efficiency at low duty cycles, thereby reducing conduction losses in the switches. Its interleaved structure ensures current sharing, while the switches experience both low voltage and low current stress, further decreasing conduction losses.

Some estimates for commutators of the fractional maximal function on stratified Lie groups

open access: yesJournal of Inequalities and Applications, 2023
In this paper, the main aim is to consider the boundedness of the nonlinear commutator [ b , M α ] $[b, M_{\alpha}]$ and the maximal commutator M α , b $M_{\alpha ,b}$ on the Lebesgue spaces over some stratified Lie group G $\mathbb{G}$ when the symbol b

On the Q $Q$‐Polynomial Property of Bipartite Graphs Admitting a Uniform Structure

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT Let Γ ${\rm{\Gamma }}$ denote a finite, connected graph with vertex set X $X$. Fix x ∈ X $x\in X$ and let ε ≥ 3 $\varepsilon \ge 3$ denote the eccentricity of x $x$. For mutually distinct scalars { θ i * } i = 0 ε ${\{{\theta }_{i}^{* }\}}_{i=0}^{\varepsilon }$ define a diagonal matrix A * = A * ( θ 0 * , θ 1 * , … , θ ε * ) ∈ Mat X ( R ) ${A}^

Instrumental evaluation of traction machines sparking

open access: yesMATEC Web of Conferences, 2017
In the article, the authors considered the possibility of the sparking monitoring at a commutator of a traction motor under operating conditions. The authors developed a method for the evaluation of sparking level at the commutator by means of the ...
