Elementary Number Theory, Group Theory and Ramanujan Graphs
Av Giuliana Davidoff, Peter Sarnak m. fl.
Häftad, 2003
716 kr
Lägg i varukorg
This text is a self contained treatment of expander graphs and in particular their explicit construction. Expander graphs are both highly connected but sparse, and besides their interest within combinatorics and graph theory, they also find various applications in computer science and engineering. …

Kazhdan's Property (T)
Av Bachir Bekka, Pierre de la de la Harpe m. fl.
Inbunden, 2008

Lägg i varukorg
Property (T) is a rigidity property for topological groups, first formulated by D. Kazhdan in the mid 1960's with the aim of demonstrating that a large class of lattices are finitely generated. Later developments have shown that Property (T) plays an important role in an amazingly large variety of …
Groups with the Haagerup Property
Gromov’s a-T-menability

A locally compact group has the Haagerup property, or is a-T-menable in the sense of Gromov, if it admits a proper isometric action on some affine Hilbert space. As Gromov's pun is trying to indicate, this definition is designed as a strong negation to Kazhdan's property (T), characterized by the …

Proper Group Actions and the Baum-Connes Conjecture
Av Guido Mislin, Alain Valette
Häftad, 2003
366 kr
Lägg i varukorg
A concise introduction to the techniques used to prove the Baum-Connes conjecture. The Baum-Connes conjecture predicts that the K-homology of the reduced C^*-algebra of a group can be computed as the equivariant K-homology of the classifying space for proper actions. The approach is expository, but …

Lägg i varukorg
A quick description of the conjecture The Baum-Connes conjecture is part of Alain Connes'tantalizing "noncommuta- tive geometry" programme [18]. It is in some sense the most "commutative" part of this programme, since it bridges with classical geometry and topology. Let r be a countable group. The …
