Now in paperback, this popular book gives a self-contained presentation
of a number of recent results, which relate the volume of convex bodies
in n-dimensional Euclidean space and the geometry of the corresponding
finite-dimensional normed spaces. The methods employ classical ideas
from the theory of convex sets, probability theory, approximation
theory, and the local theory of Banach spaces. The first part of the
book presents self-contained proofs of the quotient of the subspace
theorem, the inverse Santalo inequality and the inverse Brunn-Minkowski
inequality. In the second part Pisier gives a detailed exposition of the
recently introduced classes of Banach spaces of weak cotype 2 or weak
type 2, and the intersection of the classes (weak Hilbert space). This
text will be a superb choice for courses in analysis and probability
theory.
