Infinity of solutions to initial‐boundary value problems for linear constant‐coefficient evolution PDEs on semi‐infinite intervals

Bulletin of the London Mathematical Society
In this short communication, we announce an algorithmic procedure for constructing non‐uniqueness counter‐examples of classical solutions to initial‐boundary‐value problems for a wide class of linear evolution partial differential equations (PDE), of any

On Computation of Approximate Solutions to Large-Scale Backstepping Kernel Equations via Continuum Approximation

Systems & control letters (Print)
We provide two methods for computation of continuum backstepping kernels that arise in control of continua (ensembles) of linear hyperbolic PDEs and which can approximate backstepping kernels arising in control of a large-scale, PDE system counterpart ...

Nonlocal symmetry analysis, exact solutions, and evolution of nonlinear waves for one-dimensional shallow water magnetohydrodynamics equations

The Physics of Fluids
In this article, we study the symmetry analysis for a system of hyperbolic quasilinear partial differential equations (PDEs) that describe one-dimensional shallow water magnetohydrodynamics (SMHD) and examine its evolutionary behavior of nonlinear waves.

An analytical study on the influence of magnetic field-dependent viscosity on viscous and ohmic dissipative second-grade fluid boundary layers

Physica Scripta
This article aims to investigate the magnetohydrodynamic (MHD) boundary layer flow of a second-grade non-Newtonian fluid over a horizontally stretching sheet, considering magnetic field-dependent (MFD) viscosity, as well as viscous and Ohmic dissipations.

Interconnection and Damping Assignment Passivity-Based Control Without Partial Differential Equations

Control
Interconnection and damping assignment (IDA) is a popular passivity-based control (PBC) technique. This nonlinear control approach has proven suitable for stabilizing a wide range of systems.

Simulation of Nonlinear and Nonisothermal Reactive Liquid Chromatography considering Finite Mass-Transfer Rates and Various Adsorption Scenarios

ACS Omega
A multicomponent nonisothermal lumped kinetic model (LKM) of fixed-bed liquid chromatographic reactor is introduced and numerically approximated. The model incorporates nonlinear Bi-Langmuir and Toth adsorption isotherms, reaction kinetics, axial and ...

Nonlinear dynamic wave pattern analysis of the time-fractional Benjamin–Ono equation in ion-acoustic wave

Modern physics letters B
The study of nonlinear fractional-order partial differential equations (PDEs) and its numerous analyses of soliton solutions have been helpful in the development of engineering and physical science.

Analytical Solution of 3D Consolidation with Mixed Drainage Boundaries using the Fourier Transform Technique

Journal of Hunan University Natural Sciences
This study investigates the application of Fourier transform methods to address the partial differential equations (PDEs) encountered in three-dimensional consolidation issues in soil mechanics. The aim of this study is to derive a closed-form analytical
