Functional Equations Solving Initial-Value Problems of Complex Burgers-Type Equations for One-Dimensional Log-Gases

نویسندگان

چکیده

We study the hydrodynamic limits of three kinds one-dimensional stochastic log-gases known as Dyson's Brownian motion model, its chiral version, and Bru-Wishart process studied in dynamical random matrix theory. define measure-valued processes so that their Cauchy transforms solve complex Burgers-type equations. show applications method characteristic curves to these partial differential equations provide functional relating measures at an arbitrary time with those initial time. transform for R-transforms S-transforms measures, which play central roles free probability The obtained are simpler than useful explicit calculations including computation cumulant sequences. Some results argued using notion convolutions.

Non-polynomial Spline Method for Solving Coupled Burgers Equations

In this paper, non-polynomial spline method for solving Coupled Burgers Equations are presented. We take a new spline function. The stability analysis using Von-Neumann technique shows the scheme is unconditionally stable. To test accuracy the error norms 2L, L are computed and give two examples to illustrate the sufficiency of the method for solving such nonlinear partial differential equation...

Well-Posedness of Initial Value Problems for Functional Differential and Algebraic Equations of Mixed Type

We study the well-posedness of initial value problems for scalar functional algebraic and differential functional equations of mixed type. We provide a practical way to determine whether such problems admit unique solutions that grow at a specified rate. In particular, we exploit the fact that the answer to such questions is encoded in an integer n. We show how this number can be tracked as a p...
