Description


This textbook provides a thorough-yet-accessible introduction to function spaces, through the central concepts of integrability, weakly differentiability and fractionally differentiability.

In an essentially self-contained treatment the reader is introduced to Lebesgue, Sobolev and BV-spaces, before being guided through various generalisations such as Bessel-potential spaces, fractional Sobolev spaces and Besov spaces. Written with the student in mind, the book gradually proceeds from elementary properties to more advanced topics such as lower dimensional trace embeddings, fine properties and approximate differentiability, incorporating recent approaches. Throughout, the authors provide careful motivation for the underlying concepts, which they illustrate with selected applications from partial differential equations, demonstrating the relevance and practical use of function spaces.

Assuming only multivariable calculus and elementary functional analysis, as conveniently summarised in the opening chapters, A Course in Function Spaces is designed for lecture courses at the graduate level and will also be a valuable companion for young researchers in analysis.

About the Author


Dominic Breit is Chair of Mathematical Modelling at the Institute of Mathematics of the Clausthal University of Technology. His research interests range from pure topics such as Sobolev spaces, regularity theory for nonlinear PDEs and the calculus of variations, to applications in fluid mechanics, in particular compressible fluids, stochastic Navier-Stokes equations and fluid-structure interaction. Franz Gmeineder holds the tenure-track professorship "Theory of Partial Differential Equations" at the Department of Mathematics of the University of Konstanz, Germany. His research interests are centered around regularity theory in the Calculus of Variations, with a particular focus on linear growth functionals, real analysis and L1-based function spaces.
