An Explicit Form of Ramp Function

open access: yesAppliedMath, 2023
In this paper, an analytical exact form of the ramp function is presented. This seminal function constitutes a fundamental concept of the digital signal processing theory and is also involved in many other areas of applied sciences and engineering.

Development of Mathematical Models in Explicit Form for Design and Analysis of Axial Flux Permanent Magnet Synchronous Machines

open access: yesApplied Sciences, 2020
This article proposes a methodology for the design of double-sided coreless axial flux permanent magnet synchronous machines, which is based on a developed model for calculating the axial component of the magnetic flux density in the middle of the ...

Integer composition, connection Appell constants and Bell polynomials

open access: yesJournal of Numerical Analysis and Approximation Theory, 2021
We introduce an explicit form of the connection coefficients for Appell polynomial sequences via Toeplitz-Hessenberg matrix determinants. Generalizing, we give an explicit form of the connection coefficients for arbitrary   polynomial sequences and ...

Certain Properties and Applications of Δh Hybrid Special Polynomials Associated with Appell Sequences

open access: yesFractal and Fractional, 2023
The development of certain aspects of special polynomials in line with the monomiality principle, operational rules, and other properties and their aspects is obvious and indisputable. The study presented in this paper follows this line of research.

An explicit form for Kerov’s character polynomials [PDF]

open access: yesTransactions of the American Mathematical Society, 2007
Kerov considered the normalized characters of irreducible representations of the symmetric group, evaluated on a cycle, as a polynomial in free cumulants. Biane has proved that this polynomial has integer coefficients, and made various conjectures. Recently, Śniady has proved Biane’s conjectured explicit form for the first family of nontrivial terms in

Explicit Plancherel Formula for the Space of Symplectic Forms [PDF]

open access: yesInternational Mathematics Research Notices, 2021
Abstract We provide a Plancherel decomposition for the space of symplectic bilinear forms of rank $2n$ over a local non-Archimedean field $F$ in terms of that of $\operatorname{GL}_n(F)$.
