In mathematics, a partial differential equation (PDE) is an equation which involves a multivariable function and one or more of its partial derivatives.. The function is often thought of as an "unknown" that solves the equation, similar to how x is thought of as an unknown number solving, e.g., an algebraic equation like x 2 − 3x + 2 = 0.
Then, the above equations are written as ... H. Asmar, Nakhle (2005). Partial differential equations with Fourier series and boundary value problems. Upper Saddle ...

Here we assume that the reader is familiar with partial differential equations. We will be solving the partial differential equation u xx + u yy = f (**) We impose boundedness at infinity. We decompose the domain R² into two overlapping subdomains H 1 = (− ∞,1] × R and H 2 = [0,+ ∞) × R. In each subdomain, we will be solving a BVP of ...
Regularity is a topic of the mathematical study of partial differential equations(PDE) such as Laplace's equation, about the integrability and differentiability of weak solutions. Hilbert's nineteenth problem was concerned with this concept. [1] The motivation for this study is as follows. [2]
Partial derivatives appear in thermodynamic equations like Gibbs-Duhem equation, in quantum mechanics as in Schrödinger wave equation, as well as in other equations from mathematical physics. The variables being held constant in partial derivatives here can be ratios of simple variables like mole fractions x i in the following example ...
Duhamel's principle is the result that the solution to an inhomogeneous, linear, partial differential equation can be solved by first finding the solution for a step input, and then superposing using Duhamel's integral. Suppose we have a constant coefficient, m-th order inhomogeneous ordinary differential equation.
