Abstract: Significant achievements have been made in the analysis of linear coupled differential-difference systems (CDDSs). However, the study of nonlinear CDDSs, particularly those with time-varying ...

This program is an interactive plot of two coupled homogeneous linear differential equations. To use this program, you first need to have Python 3 with Tkinter ...

Dimsym is a program primarily for the determination of symmetries of differential equations. It also can be used to compute symmetries of distributions of vector fields or differential forms on finite ...

Abstract: Differential-algebraic equations (DAEs) arise naturally as a result of equation-based object-oriented modeling. In many cases, these models contain unknown parameters that have to be ...

This book is an introduction to the general theory of second order parabolic differential equations, which model many important, time-dependent physical systems. It studies the existence, uniqueness, ...

This comprehensive volume presents essential mathematical results devoted to topics of mathematical analysis, differential equations and their various applications. It focuses on differential ...

By coupling electronic-structure methods with the resolution of the time-dependent Schrödinger equation, we developed and implemented the time-resolved induced density of the electronic wavepacket, ...
