**Applied functional analysis. Exercises by Bernard Cornet and Jean-Michel Lasry. Transl. by Carole Labrousse.
2nd ed.**

The first English edition of this book appeared in 1979, cf. Zbl 0424.46001. The second edition has made some additions and some deletions. Its contents are best described as introduction to functional analysis with applications. All the functional analysis centres around the theory of Hilbert spaces of various sorts introduced in the first five chapters. The next four chapters specialize the theory to study Sobolev spaces. The last part, made up of seven chapters, consists of diverse applications: convex analysis, spectral theory, boundary value problems, Nagumo’s theorem (a theorem in the theory of ordinary differential equations with varied applications), first-order partial differential equations. Many areas of application are alluded to although not actually developed.
