In mathematical physics and engineering, Trefftz approximations by definition involve functions that satisfy the underlying differential equation of the problem (as well as the interface boundary conditions). Examples include harmonic polynomials for the Laplace equation; plane waves, cylindrical or spherical harmonics for wave problems; exponential functions for boundary layers, and so on. Trefftz approximations are well established in the context of pseudospectral and domain decomposition methods, but this talk calls attention to applications that are known less well or are entirely new:
This discussion of the versatility and power of Trefftz methods is intended to stimulate their application in many other areas of applied science and engineering.
