This book studies the existence and uniqueness of solutions to parabolic-type equations with irregular coefficients and/or initial conditions. It elaborates on the DiPerna-Lions theory of renormalized solutions to linear transport equations and related equations, and also examines the connection between the results on the partial differential equation and the well-posedness of the underlying stochastic/ordinary differential equation.
Parabolic Partial Differential Equations with Irregular Data. Related Issues. Application to Stochastic Differential Equations
"We study the existence and the uniqueness of the solution to parabolic type equations with irregular coefficients and/or initial conditions. The coefficients considered in the equation typically belong to Lebesgue or Sobolev spaces, the initial condition may be only Lebesgue integrable, the second order term in the equation may be degenerate. The arguments elaborate on the DiPerna-Lions theory of renormalized solutions to linear transport equations and related equations. The connection between the results on the partial differential equation and the well-posedness of the underlying stochastic/ordinary differential equation is examined. We in particular follow up on two previous articles. These notes, written up jointly by the two authors, lay out the background on the various issues and present the recent results obtained by the second author. They are an expanded version of the lectures delivered at Collège de France during the academic year 2012-13." [résumé de la page de titre].

This book delves into the recent findings and research methods in the existence and regularity theory for Non-Newtonian Fluids with Variable Power-Law. The aim of this book is not only to introduce recent results and research methods in the existence and regularity theory, such as higher integrability, higher differentiability, and Holder continuity for flows of non-Newtonian fluids with variable power-laws, but also to summarize much of the existing literature concerning these topics. While this book mainly focuses on steady-state flows of non-Newtonian fluids, the methods and ideas presented in this book can be applied to unsteady flows (as discussed in Chapter 7) and other related problems such as complex non-Newtonian fluids, plasticity, elasticity, p(x)-Laplacian type systems, and so on. The book is intended for researchers and graduate students in the field of mathematical fluid mechanics and partial differential equations with variable exponents. It is expected to contribute to the advancement of mathematics and its applications.
