Paperback. Etat : New. This book targets graduate students and researchers who want to learn about Lebesgue spaces and solutions to hyperbolic equations. It is divided into two parts.Part 1 provides an introduction to the theory of variable Lebesgue spaces: Banach function spaces like the classical Lebesgue spaces but with the constant exponent replaced by an exponent function. These spaces arise naturally from the study of partial differential equations and variational integrals with non-standard growth conditions. They have applications to electrorheological fluids in physics and to image reconstruction. After an introduction that sketches history and motivation, the authors develop the function space properties of variable Lebesgue spaces; proofs are modeled on the classical theory. Subsequently, the Hardy-Littlewood maximal operator is discussed. In the last chapter, other operators from harmonic analysis are considered, such as convolution operators and singular integrals. The text is mostly self-contained, with only some more technical proofs and background material omitted. Part 2 gives an overview of the asymptotic properties of solutions to hyperbolic equations and systems with time-dependent coefficients. First, an overview of known results is given for general scalar hyperbolic equations of higher order with constant coefficients. Then strongly hyperbolic systems with time-dependent coefficients are considered. A feature of the described approach is that oscillations in coefficients are allowed. Propagators for the Cauchy problems are constructed as oscillatory integrals by working in appropriate time-frequency symbol classes. A number of examples is considered and the sharpness of results is discussed. An exemplary treatment of dissipative terms shows how effective lower order terms can change asymptotic properties and thus complements the exposition.…

Paperback. Etat : New. This memoir is devoted to the development of the theory of pseudo-differential operators with respect to a sub-Riemannian structure on an arbitrary compact Lie group. Our approach recovers the elliptic theory developed by the second author and V Turunen which in some sense is a theory of pseudo-differential operators adapted to the Laplacian on a compact Lie group. This means that the Hörmander classes are defined in terms of the spectrum of the Laplacian and they are compatible with the sharp analysis of elliptic problems. Indeed, in the latter case, the decay or growth of the symbols and their derivatives/differences is measured in terms of the spectrum of the Laplacian. However, in the setting of the subelliptic classes that we develop here, such a decay or growth is measured in terms of the spectrum of a Hörmander sub-Laplacian and then our theory allows the sharp analysis of subelliptic problems.Published by Mathematical Society of Japan and distributed by World Scientific Publishing Co. for all markets.…
