* The denoising algorithms in [[nonlocal image processing]] are able to detect patterns in a better way than the PDE based models. A simple model for denoising is the [[nonlocal mean curvature flow]].  * The denoising algorithms in [[nonlocal image processing]] are able to detect patterns in a better way than the PDE based models.

* The [[Boltzmann equation]] models the evolution of dilute gases and it is intrinsically an integral equation. In fact, simplified [[kinetic models]] can be used to derive the [[fractional heat equation]] without resorting to stochastic processes.  * The [[Boltzmann equation]] models the evolution of dilute gases and it is intrinsically an integral equation.

  * In conformal geometry,  +  * In conformal geometry, the Paneitz operators $\mathcal{P}(s)$ encode information about the manifold, when the parameter is not an even integer they are fractional powers of the Laplacian, and therefore are nonlocal. 
* In oceanography, the temperature on the surface may diffuse though the atmosphere giving rise to the [[surface quasigeostrophic equation]].  * In oceanography, the temperature on the surface may diffuse though the atmosphere giving rise to the [[surface quasigeostrophic equation]].  
* Several stochastic models, in particular particle systems, can be used to derive nonlocal equations like the [[Nonlocal porous medium equation]], the [[HamiltonJacobi equation with fractional diffusion]], [[conservation laws with fractional diffusion]], etc...  * Several stochastic models, in particular particle systems, can be used to derive nonlocal equations like the [[Nonlocal porous medium equation]], the [[HamiltonJacobi equation with fractional diffusion]], [[conservation laws with fractional diffusion]], etc...
