SUMMARY

The discussion highlights the Kuramoto–Sivashinsky equation, a fourth-order partial differential equation (PDE) utilized in modeling flame dynamics. It also references the Korteweg–de Vries (KdV) soliton equation, significant in nonlinear physics, and the Euler-Bernoulli beam theory, which describes one-dimensional transverse waves in slender beams. These examples illustrate the practical applications of high-order PDEs in various scientific fields.

Came across this today, a fourth order PDE - the Kuramoto–Sivashinsky equation, apparently used to model flames

https://en.wikipedia.org/wiki/Kuramoto–Sivashinsky_equation

Any other examples of high order PDEs with actual applications?
