Rational Points and Arithmetic of Fundamental Groups
Springer Berlin (Verlag)
978-3-642-30673-0 (ISBN)
This monograph begins by laying the foundations for the space of sections of the fundamental group extension of an algebraic variety. Then, arithmetic assumptions on the base field are imposed and the local-to-global approach is studied in detail. The monograph concludes by discussing analogues of the section conjecture created by varying the base field or the type of variety, or by passing to a characteristic quotient of the fundamental group extension or its birational analogue.

From the book reviews:
"The book under review, resulting from the author's dissertation ... is both a research monograph and a thorough presentation of the arithmetic and geometry of Grothendieck's section conjecture from the foundations to the current state of the art. ... It will be useful not only to specialists, as it is accessible to anyone familiar with the basics of modern algebraic geometry and the theory of algebraic fundamental groups." (Marco A.
