Based on the traditional scalar auxiliary variable (SAV) method, the exponential SAV (ESAV)
method, and the Lagrange multiplier method, three efficient energy stable schemes are …

The paper aims to study the numerical solution of the Zakharov-Rubenchik equations on
unbounded domains, which model the propagation of two kinds of waves in plasma physics …

With the continuous development in the field of deep learning, in recent years, it has also
been widely used in the field of solving partial differential equations, especially the physics …

The Riesz space-fractional derivative is discretized by the Fourier pseudo-spectral (FPS)
method. The Riesz space-fractional nonlinear Klein–Gordon–Zakharov (KGZ) and Klein …

In this paper, based on the paradigm of supplementary variable method (SVM), we
reformulate the Klein–Gordon–Zakharov system into equivalent optimization problem …

In this paper we develop a time splitting combined with exponential wave integrator (EWI)
Fourier pseudospectral (FP) method for the quantum Zakharov system (QZS), ie using the …

Every year hundreds of serious accidents and catastrophic are accompanied by mining
sector services as disaster, flooding, and demolition. To reduce the severity of the results …

Innovation is generally the main driver of most technological developments. This work deals
with a typical example in the communication sector, through the development of some …
