Noncompact symmetric and locally symmetric spaces naturally appear in
many mathematical theories, including analysis (representation theory,
nonabelian harmonic analysis), number theory (automorphic forms),
algebraic geometry (modulae) and algebraic topology (cohomology of
discrete groups). The main purpose of this book is to introduce uniform
constructions of most of the known compactifications with emphasis on
their geometric and topological structures. Familiarity with the theory
of semisimple Lie groups is assumed, as is familiarity with algebraic
groups defined over the rational numbers in later parts of the book,
although most of the pertinent material is recalled as presented.
Otherwise, the book is a self-contained reference aimed at graduate
students and research mathematicians interested in the applications of
Lie theory and representation theory to diverse fields of mathematics.
