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. This special issue is devoted to the analysis of partial differential models in fluid dynamics and related areas.

Key topics in nonlinear partial differential equations as well as several fundamental tools and methods are presented. The only prerequisite required is a … Gregory Beylkłn, James M. Keiser, in Wavelet Analysis and Its Applications, 1997. Abstract. We numerically solve nonlinear partial differential equations of the form u t = ℒ u + N f u, where ℒ and N are linear differential operators and f(u) is a nonlinear function.Equations of this form arise in the mathematical description of a number of phenomena including, for example, signal 2020-06-07 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 video is useful for students of BTech/BSc/MSc Mathematics students. Also for students preparing IIT-JAM, GATE, CSIR-NET and other exams.

No heat is transferred from the other three edges since the edges are insulated. 2019-02-01 · Let us start by concentrating on the problem of computing data-driven solutions to partial differential equations (i.e., the first problem outlined above) of the general form (2) u t + N [u] = 0, x ∈ Ω, t ∈ [0, T], where u (t, x) denotes the latent (hidden) solution, N [⋅] is a nonlinear differential operator, and Ω is a subset of R D. This paper contributes to investigate the Jacobi spectral and pseudo-spectral Galerkin techniques to solve a general form of nonlinear weakly singular Volterra integro-differential equations of the first order. By applying some suitable change of variables, we have made the solution of the mentioned equations to be smooth. Then, by applying the spectral and pseudo-spectral Jacobi Galerkin 2017-08-02 · While there is currently a lot of enthusiasm about "big data", useful data is usually "small" and expensive to acquire. In this paper, we present a new paradigm of learning partial differential equations from {\\em small} data. In particular, we introduce \\emph{hidden physics models}, which are essentially data-efficient learning machines capable of leveraging the underlying laws of physics 2021-03-30 · The Krein-Rutman theorem plays a very important role in nonlinear partial differential equations, as it provides the abstract basis for the proof of the existence of various principal eigenvalues, which in turn are crucial in bifurcation theory, in topological degree calculations, and in stability analysis of solutions to elliptic equations as steady-state of the corresponding parabolic equations. The Handbook of Nonlinear Partial Differential Equations is the latest in a series of acclaimed handbooks by these authors and presents exact solutions of more than 1600 nonlinear equations encountered in science and engineering--many more than any other book available.
