Recent developments in the Navier-Stokes problem. (English) Zbl 1034.35093
Chapman & Hall/CRC Research Notes in Mathematics 431. Boca Raton, FL: Chapman & Hall/CRC (ISBN 1-58488-220-4/pbk). xii, 395 p. (2002).
From the author’s introduction: This book is a self-contained exposition of recent results on the Navier-Stokes equations, presented from the point of view of real harmonic analysis. A quarter of the book is an introduction to real harmonic analysis, where all the material needed in the book is introduced and proved.
The Navier-Stokes equations are examined in a very restricted setting: \[ \rho\delta_t\vec u=\mu \Delta\vec u-\rho(\vec u. \vec\Delta)\vec u-\vec\nabla p, \] \[ \vec\nabla\cdot\vec u=0, \] that is a viscous, homogeneous, incompressible fluid that fills the entire space and is not submitted to external forces. The contents of the book in more detail:
Part I is devoted to the recalling of some (presumably) well-known results of harmonic analysis on some special spaces of functions or distributions, and on some convolution operators (fractional integration, Calderón-Zygmund operators, Riesz transforms, etc.). In Parts 2 to 6, those tools are applied to the study of the Cauchy problem for the Navier-Stokes equations: Part 2 presents some general shift-invariant estimates for the Navier-Stokes equations; Part 3 reviews the classical existence results of Leray (weak solutions \(\vec u\) such that \(\vec u\in L^\infty((0,\infty)\), \((L^2)^d)\), \(\vec\nabla \otimes\vec u\in L^2((0,\infty), (L^2)^{d^2})\) and Kato and Fujita (mild solutions in \({\mathcal C}([0,T]\), \((H^s)^d)\), \(s\geq d/2-1\), or in \({\mathcal C}([0,T], (L^p)^d)\), \(p\geq d\); Part 4 and 5 describe some recent results on mild solutions (generalizations of Kato’s results), including the theorem of Koch and Tataru on the existence of solutions for data in \(BMO^{(-1)}\) and Cannone’s theory of self-similar solutions: Part 6 considers suitable solutions when \(d=3\), the main tool is the local energy inequality of Scheffer and the regularity criterion of Caffarelli, Kohn and Nirenberg, with applications to the study of weak solutions with infinite energy.
