The present book is devoted to a study of relative Prüfer rings and
Manis valuations, with an eye to application in real and p-adic
geometry. If one wants to expand on the usual algebraic geometry over a
non-algebraically closed base field, e.g. a real closed field or
p-adically closed field, one typically meets lots of valuation domains.
Usually they are not discrete and hence not noetherian. Thus, for a
further develomemt of real algebraic and real analytic geometry in
particular, and certainly also rigid analytic and p-adic geometry, new
chapters of commutative algebra are needed, often of a non-noetherian
nature. The present volume presents one such chapter.
