Moreover, it is known since Kolmogorov, that densities of Brownian motions follows equivalently a Fokker Planck equations, which has a convection part, but also a diffusion term, both determined entirely by this local volatility. Since r = 0 is a solution, the origin is still an equilibrium. The first argument toward non-linear effect in Market concerns what is Stokes equations can capture these phenomenas. Then, using a non-linear Fokker-Planck equation, one adds a SV component and for any given set of SV parameters computes a new "leveraged local volatility surface" that still matches the vanillas, while accommodating SV. Chapter 8 discusses A table of applications of supersymmetry in theoretical physics is also included. The equations are more interesting for \beta > 0 . But now it's not stable: if r is between 0 .. This has two solutions, r = 0 and r = \sqrt{\beta} . Indeed, this last study is a quite direct application of the the techniques developed in our previous post. Topics include: supersymmetry in the Fokker-Planck & Lengevin equations and the implications of good/broken supersymmetry. The main topics are the Witten model, supersymmetric classical mechanics, shape-invariant potentials and exact solutions, supersymmetry in classical stocastic dynamics and supersymmetry in the Pauli & Dirac equations. The SLV Calibrator then applies to this PDE solution a Levenberg-Marquardt optimizer and finds the (time bucketed) SV parameters that yield a maximally flat leveraged local volatility surface.
