Fixed point theory
Andrzej Granas, James Dugundji
Granas-Dugundji's book is an encyclopedic survey of the classical fixed point theory of continuous maps (the work of Poincaré, Brouwer, Lefschetz-Hopf, Leray-Schauder) and all its various modern extensions. This is certainly the most learned book ever likely to be published on this subject.
