Study Notes
Integral Equations and Differential Equations
- The analog to differential equations in integral equations is the integral equation, which is an equation that involves an unknown function and its definite integrals.
General Form of Integral Equations
- The general form of an integral equation is ∫K(x, s)φ(s)ds = f(x), where K(x, s) is the kernel, φ(s) is the unknown function, and f(x) is the given function.
Converting Between Differential and Integral Equations
- Differential equations can often be converted into integral equations, and vice versa, using integration by parts or the fundamental theorem of calculus.
Solving Boundary Value Problems
- One method of solving a boundary value problem is to use the Green's function, which is a fundamental solution to the boundary value problem.
Physics Applications
- Physical laws, such as the laws of thermodynamics, electromagnetism, and quantum mechanics, often have an analog integral and differential form.
Characteristics of Integral Equations
- Integral equations contain integrals of the unknown function instead of derivatives.
Convertible Equations
- Many physical laws and equations, such as Maxwell's equations, can often be converted between differential and integral equations.
Maxwell's Equations
- Maxwell's equations often have an integral form in addition to their differential form, which is used to describe the behavior of electromagnetic fields.
