Parabolic regularization of the gradient catastrophes for the Burgers-Hopf equation and Jordan chain

Non-standard parabolic regularization of the gradient catastrophes for the Burgers-Hopf equation is proposed. It is based on the analysis of all (generic and higher order) gradient catastrophes and their step-by-step regularization by embedding the Burgers-Hopf equation into the multi-component parabolic systems of the quasilinear PDEs with the most degenerate Jordan block. The probabilistic realization of such a procedure is presented. The complete regularization of the Burgers-Hopf equation is achieved by embedding it into an infinite parabolic Jordan chain. It is shown that the Burgers equation is a particular reduction of the Jordan chain. Gradient catastrophes for the parabolic Jordan systems are also studied.
