 Schramm–Loewner evolution

In probability theory, the Schramm–Loewner evolution with parameter "κ", also known as stochastic Loewner evolution (SLE"κ"), is a family of random planar curves that have been proven to be the scaling limit of a variety of two-dimensional lattice models in statistical mechanics.Given a parameter "κ" and a domain in the complex plane "U", it gives a family of random curves in "U", with "κ" controlling how much the curve turns.
