Hybrid expansion methods for fractional non-linear mathematical systems with Erdelyi-Kober derivative operators in theory of tsunami wave modeling [PDF]

Scientific Reports
This work develops two hybrid semi-analytical methods, namely the expansion new iterative method (ENIM) and the expansion homotopy perturbation method (EHPM), for solving the fractional Whitham-Broer-Kaup equations (WBKEs) involving the Erdélyi-Kober (EK)

Mapping properties of nonlinear integral operators and pre-Schwarzian derivatives [PDF]

Journal of Mathematical Analysis and Applications, 2004
Let \(A\) be the class of functions analytic in the unit disk \({\mathbf D}= \{{\mathbf z}:|{\mathbf z}|< 1\}\) and normalized by \(f(0)= 0\), \(f'(0)= 1\). In 1969 Hornich investigated the operators \[ f\oplus g(z)= \int^z_0 f'(w) g'(w)\,dw;\quad \alpha* f(z)= \int^z_0 (f'(w))^\alpha\, dw \] acting for \(f,g\in LU\) (locally univalent functions from \(

Quantitative approximation by nonlinear Angheluta-Choquet singular integrals

Journal of Numerical Analysis and Approximation Theory, 2020
By using the concept of nonlinear Choquet integral with respect to a capacity and as a generalization of the Poisson-Cauchy-Choquet operators, we introduce the nonlinear Angheluta-Choquet singular integrals with respect to a family of submodular set ...

The regularity properties and blow-up of the solutions for improved Boussinesq equations

Electronic Journal of Qualitative Theory of Differential Equations, 2021
In this paper, we study the Cauchy problem for linear and nonlinear Boussinesq type equations that include the general differential operators. First, by virtue of the Fourier multipliers, embedding theorems in Sobolev and Besov spaces, the existence ...

Approximate Diagonal Integral Representations and Eigenmeasures for Lipschitz Operators on Banach Spaces

Mathematics, 2022
A new stochastic approach for the approximation of (nonlinear) Lipschitz operators in normed spaces by their eigenvectors is shown. Different ways of providing integral representations for these approximations are proposed, depending on the properties of
