Non-perturbative
text:
In mathematics and physics, a non-perturbative function or process is one that cannot be described by perturbation theory. An example is the function which does not equal its own Taylor series in any neighborhood around x = 0. Every coefficient of the Taylor expansion around x = 0 is exactly zero, but the function is non-zero if x ≠ 0. In physics, such functions arise for phenomena which are impossible to understand by perturbation theory, at any finite order. In quantum field theory, 't Hooft–P
