Etingof, Pavel (ed.) et al., The unity of mathematics. In honor of the ninetieth birthday of I. M. Gelfand. Papers from the conference held in Cambridge, MA, USA, August 31–September 4, 2003. Boston, MA: Birkhäuser (ISBN 0-8176-4076-2/hbk). Progress in Mathematics 244, 173-204 (2006).
The purpose of this remarkable survey is to outline the philosophy of noncommutative geometry and to describe “a few of the open frontiers and problems” in this field.
The author describes the extensions of classical concepts to the noncommutative framework for measure theory, topology, differential geometry and Riemannian geometry. The paper has the following sections: The framework of noncommutative geometry; Measure theory; Topology; Differential geometry; Quantized calculus; Metric geometry and spectral action; Metric geometry, the local index formula; Renormalization, residues, and locality; Modular forms and the space of $$\mathbb Q$$-lattices. It also has a rich bibliography which is useful for researchers who are interested in one of the most fascinating branches of mathematics.
