متن کاملL2-Invariants and Their Applications to Geometry, Group Theory and Spectral Theory
During the last decades mathematics has developed at an incredible speed and a large amount of new information and results have been accumulated. Therefore mathematics faces the problem that it breaks up into different areas which may not communicate among one another. Fortunately recent developements go in the opposite direction. In particular interactions of different fields have turned out t...
متن کاملL-invariants of locally symmetric spaces
Let X = G/K be a Riemannian symmetric space of the noncompact type, Γ ⊂ G a discrete, torsion-free, cocompact subgroup, and let Y = Γ\X be the corresponding locally symmetric space. In this paper we explain how the Harish-Chandra Plancherel Theorem for L(G) and results on (g,K)-cohomology can be used in order to compute the L-Betti numbers, the Novikov-Shubin invariants, and the L-torsion of Y ...
متن کامل“ L 2 - torsion and 3 - manifolds ” by Wolfgang Lück
We introduce for a finite CW -complex whose L2-Betti numbers are all trivial and whose Novikov-Shubin invariants are all positive a positive real number called combinatorial L2-torsion. It behaves like a “multiplicative Euler characteristic”. Tools for the computations of L2-Betti numbers, Novikov-Shubin invariants, Fuglede-Kadison determinant and combinatorial L2-torsion are given. For example...
متن کاملL-Invariants from the Algebraic Point of View
We give a survey on L-invariants such as L-Betti numbers and Ltorsion taking an algebraic point of view. We discuss their basic definitions, properties and applications to problems arising in topology, geometry, group theory and K-theory.
