A kind of identities related to Riemann zeta-function

open access: yesOpen Mathematics
The main purpose of this paper is to study a kind of identities related to Riemann zeta-function. We first construct a new sequence involving trigonometric function.

Estructura de superficies de Riemann, desigualdades isoperimétricas y medida p-armónica en grafos [PDF]

open access: yes, 1999
Se estructura el trabajo en torno a un capítulo introductorio y cinco capítulos temáticos que desarrollan teorías referidas a la descomposición de superficies, a la desigualdad isopemétrica en superficies de Riemann con punturas, a la desigualdad ...

Nonclassical shock waves of conservation laws: Flux function having two inflection points

open access: yesElectronic Journal of Differential Equations, 2006
We consider the Riemann problem for non-genuinely nonlinear conservation laws where the flux function admits two inflection points. This is a simplification of van der Waals fluid pressure, which can be seen as a function of the specific volume for a ...

Discrete universality theorem for Matsumoto zeta-functions and nontrivial zeros of the Riemann zeta-function

open access: yesMathematical Modelling and Analysis
In 2017, Garunkštis, Laurinčikas and Macaitienė proved the discrete universality theorem for the Riemann zeta-function shifted by imaginary parts of nontrivial zeros of the Riemann zeta-function.

Sliding Mode Control in Aerospace Applications: A Survey

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Solving the solution of Goursat problem using the Riemann method for a system of fourth order hyperbolic differential equations

open access: yesВестник Самарского университета: Естественнонаучная серия
Boundary value problems for certain systems of hyperbolic-type differential equations can be effectively solved using the Riemann method. In this paper, we consider an approach for constructing the Riemann matrix for a system of fourth order hyperbolic ...

The Extension of the Riemann’s Zeta Function

open access: yesInternational Journal of Basic Sciences and Applied Computing
In mathematics, the search for exact formulas giving all the prime numbers, certain families of prime numbers or the n-th prime number has generally proved to be vain, which has led to contenting oneself with approximate formulas [8]. The purpose of this article is to give a new proof of the Riemann hypothesis [4]-which is closely related to the ...

Riemann Invariants and Rank-k Solutions of Hyperbolic Systems [PDF]

open access: yes, 2006
In this paper we employ a "direct method" in order to obtain rank-k solutions of any hyperbolic system of first order quasilinear differential equations in many dimensions.

Nasal Epithelial Immune Signatures Are Associated With Age‐Dependent Asthma Trajectories in Early Life

open access: yesAllergy, EarlyView.
Nasal epithelial transcriptomics identified three cytokine‐associated epithelial immune programs linked to childhood asthma phenotypes. Age‐associated epithelial polarization shifted from IFN/type‐17‐associated toward type‐2‐associated programs after 3 years of age.

Stieltjes–Bethe equations in higher genus and branched coverings with even ramifications

open access: yesNuclear Physics B, 2018
We describe projective structures on a Riemann surface corresponding to monodromy groups which have trivial SL(2) monodromies around singularities and trivial PSL(2) monodromies along homologically non-trivial loops on a Riemann surface.
