## 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.
