Linear Sturm-Liouville problems with Riemann-Stieltjes integral boundary conditions [PDF]

open access: diamondOpuscula Mathematica, 2018
We study second-order linear Sturm-Liouville problems involving general homogeneous linear Riemann-Stieltjes integral boundary conditions. Conditions are obtained for the existence of a sequence of positive eigenvalues with consecutive zero counts of the

The Existence of Positive Solutions for a p-Laplacian Tempered Fractional Diffusion Equation Using the Riemann–Stieltjes Integral Boundary Condition

open access: goldMathematics
In this paper, we focus on the existence of positive solutions for a class of p-Laplacian tempered fractional diffusion equations involving a lower tempered integral operator and a Riemann–Stieltjes integral boundary condition. By introducing certain new

A new theorem on the existence of the Riemann-Stieltjes integral and an improved version of the Lo\'eve-Young inequality [PDF]

open access: gold, 2015
Using the notion of the truncated variation we obtain a new theorem on the existence and estimation of the Riemann-Stieltjes integral. As a special case of this theorem we obtain an improved version of the Lo\'{e}ve-Young inequality for the Riemann ...

Two-Point Quadrature Rules for Riemann–Stieltjes Integrals with Lp–error estimates [PDF]

open access: diamondMoroccan Journal of Pure and Applied Analysis, 2018
In this work, we construct a new general two-point quadrature rules for the Riemann–Stieltjes integral ∫abf(t) du (t)$\int_a^b {f(t)} \,du\,(t)$, where the integrand f is assumed to be satisfied with the Hölder condition on [a, b] and the integrator u is
