Integraalvõrranditeks
Integraalvõrranditeks are mathematical equations where the unknown function appears under an integral sign. They are a generalization of algebraic equations and differential equations. In their simplest form, an integral equation involves an unknown function, say $y(x)$, and an integral of this function, possibly multiplied by a known kernel function, that is set equal to another known function.
There are several types of integral equations. Fredholmi integraalvõrrandid are characterized by fixed integration limits, typically
Furthermore, integral equations can be classified as linear or nonlinear, depending on whether the unknown function
