In this article, the homotopy analysis method is applied to solve nonlinear fractional partial differential equations. On the basis of the homotopy analysis method, a scheme is developed to obtain the approximate solution of the fractional KdV, K (2,2), Burgers, BBM‐Burgers, cubic Boussinesq, coupled KdV, and Boussinesq‐like B ( m, n) equations with initial conditions, which are introduced by replacing some integer‐order time derivatives by fractional derivatives.

Nonlinear partial differential equations are the most fundamental models in studying nonlinear phenomena. This special issue is devoted to the analysis of partial differential models in fluid dynamics and related areas. It consists of eight papers. Example (3.2) Consider the following nonlinear partial differential equation: ∂ u ∂ t = ∂ u ∂ x 2 + u ∂ 2 u ∂ x 2, u x .0 = x 2 E24. Taking Laplace transform of Eq. (24), subject to the initial condition, we have: ℓ u x t = x 2 s + 1 s ℓ ∂ u ∂ x 2 + u ∂ 2 u ∂ x 2. Take the inverse Laplace transform to find that: Although the origin of nonlinear partial differential equations is very old, they have undergone remarkable new developments during the last half of the twenti- eth century. One of the main impulses for developing nonlinear partial differential equations has been the study of nonlinear wave propagation problems. Abstract.

Partial Differential Equations III: Nonlinear Equations. This volume is devoted to nonlinear PDE. There are treatments of equations arising in classical continuum mechanics, such as vibrating strings and membranes, and fluid flows. We also treat equations arising in differential geometry, nonlinear diffusion, and general relativity. Nonlinear partial differential equations are the most fundamental models in studying nonlinear phenomena.
In mathematics, a partial differential equation (PDE) is an equation which imposes relations between the various partial derivatives of a multivariable function. The function is often thought of as an "unknown" to be solved for, similarly to how x is thought of as an unknown number, to be solved for, in an algebraic equation like x2 − 3x + 2 = 0. However, it is usually impossible to write down explicit formulas for …

This book primarily concerns quasilinear and semilinear elliptic and parabolic partial differential equations, inequalities, and systems. It balances the abstract functional-analysis approach based on nonlinear monotone, pseudomonotone, weakly continuous, or accretive mappings with concrete partial differential equations in their weak (or more general) formulation.
