Fractional wave equation and damped waves [PDF]

, 2013
In this paper, a fractional generalization of the wave equation that describes propagation of damped waves is considered. In contrast to the fractional diffusion-wave equation, the fractional wave equation contains fractional derivatives of the same ...

Explicit Soliton Structure Formation for the Riemann Wave Equation and a Sensitive Demonstration

Fractal and Fractional, 2023
The motive of the study was to explore the nonlinear Riemann wave equation, which describes the tsunami and tidal waves in the sea and homogeneous and stationary media. This study establishes the framework for the analytical solutions to the Riemann wave

Solving the frequency-domain acoustic VTI wave equation using physics-informed neural networks

Geophysical Journal International, 2021
Frequency-domain wavefield solutions corresponding to the anisotropic acoustic wave equation can be used to describe the anisotropic nature of the Earth. To solve a frequency-domain wave equation, we often need to invert the impedance matrix.

Quantum algorithm for simulating the wave equation [PDF]

Physical Review A, 2017
We present a quantum algorithm for simulating the wave equation under Dirichlet and Neumann boundary conditions. The algorithm uses Hamiltonian simulation and quantum linear system algorithms as subroutines.

Gravitational-Wave Constraints on the Neutron-Star-Matter Equation of State. [PDF]

Physical Review Letters, 2017
The detection of gravitational waves originating from a neutron-star merger, GW170817, by the LIGO and Virgo Collaborations has recently provided new stringent limits on the tidal deformabilities of the stars involved in the collision.

The Q-Space Deformed Wave Equation

Complexity, 2022
Let q∈0,1. We know that, when q tends to 1, we recover “classical” quantum mechanics. However, when q is not equal to one, we have a theory of quantum mechanics in a spacetime, i.e., a theory where the vacuum has a nonzero energy density. As a q-analogue

Comparative Study on Numerical Simulation of Wave-Current Nonlinear Interaction Based on Improved Mass Source Function

Journal of Marine Science and Engineering, 2023
In coastal waters, wave propagation is often affected by rivers and tides. The wave current interaction increases the complexity of the wave propagation.

How to obtain a covariant Breit type equation from relativistic Constraint Theory [PDF]

, 1994
It is shown that, by an appropriate modification of the structure of the interaction potential, the Breit equation can be incorporated into a set of two compatible manifestly covariant wave equations, derived from the general rules of Constraint Theory ...

Wave polynomials, transmutations and Cauchy's problem for the Klein-Gordon equation [PDF]

, 2012
We prove a completeness result for a class of polynomial solutions of the wave equation called wave polynomials and construct generalized wave polynomials, solutions of the Klein-Gordon equation with a variable coefficient.

On traveling wave solutions of a class of KdV-Burgers-Kuramoto type equations

AIMS Mathematics, 2019
In the paper, the traveling wave solutions of a KdV–Burgers-Kuramoto type equation with arbitrary power nonlinearity are considered. Lie symmetry analysis method on the equation is performed, which shows that the equation possesses traveling wave ...
