In mathematics, a linear differential equation is a differential equation that is defined by a linear polynomial in the unknown function and its derivatives, that is an equation of the form where a0(x), ..., an(x) and b(x) are arbitrary differentiable functions that do not need to be linear, and y′, ..., y are the successive derivatives of an unknown function y of the variable x. Such an equation is an ordinary differential equation (ODE). A linear differential equation may als… NettetNon-linearity is a natural part of physical theories. In a flowing fluid the analogue of Newton's second law tells us how the velocity changes at a point. Some of the change must be due to the momentum carried by fluid that will arrive at the point an instant from now. In turn, this momentum, by definition depends on the velocity of the fluid.

NettetIn this paper, we investigate the fractional-order Klein–Fock–Gordon equations on quantum dynamics using a new iterative method and residual power series method based on the Caputo operator. The fractional-order Klein–Fock–Gordon equation is a generalization of the traditional Klein–Fock–Gordon equation that allows for non … Nettet1. let us take a simple operator L = d d t + y and look at the equation. (1) L y = d y d t − y 2 = 0. we can verify that y 1 = 1 1 − t and y 2 = 2 2 − t are solutions of ( 1) and y 2 ( 0) = 2 y 1 ( 0). if L were linear we would have y 2 ( t) = 2 y 1 ( t) at least on the interval common existence. do we have that?

Sometimes the application of Lagrange equation to a variable system may result in a system of nonlinear partial differential equations.

NettetA novel class of nonlinear stochastic fractional differential equations with delay and the Jumarie and Ito differentials is introduced in the paper. The aim of the study is to prove existence and uniqueness of solutions to these equations. The main results of the paper generalise some previous findings made for the non-delay and three-scale equations … NettetWe use superposition principle to account for linearity in a equation if we have a equation. f ( x) = y = 2 x. Then we can say that for x 1: y 1 = f ( x 1) = 2 x 1. and for x 2: y 2 = f ( x 2) = 2 x 2. This equation will be linear if f ( x 1 + x 2) = f ( x 1) + f ( x 2). This is the case to be observed for simple algebraic equations.
