Pentagon Relation for the Quantum Dilogarithm and Quantized ,,rove that it is preserved by the intertwiner operator defined using the quantum dilogarithm. Using this we can define a representation of the quantized moduli space of configurations of 5 points on the projective line.

Geodesic Flow on the Normal Congruence of a Minimal Surfaces. The metric is lorentz with isolated degenerate points and the flow is shown to be completely integrable. In addition, we give a new holomorphic description of minimal surfaces in ?. and relate it to the classical Weierstrass representation.

Milnor Invariants and ,-Class Groupsic Milnor numbers. As an application, we describe the Galois module structure of the .-class group of a cyclic extension of ? of degree . (. being a prime number) in terms of the arithmetic higher linking matrices. In particular, our formula generalizes the classical formula of Rédei on the 4 and 8 ranks of the 2-class group of a quadratic field.

https://doi.org/10.1007/978-3-662-36809-1J?rgensen’s inequality gives a necessary condition for a non-elementary group of M?bius transformations to be discrete. In this paper we generalise this to the case of groups of M?bius transformations of a non-Archimedean metric space. As an application, we give a version of J?rgensen’s inequality for SL(2, ?.).

https://doi.org/10.1007/978-3-642-86505-3This is a survey of higher-dimensional Kleinian groups, i.e., discrete isometry groups of the hyperbolic .-space ?. for . ≥ 4. Our main emphasis is on the topological and geometric aspects of higher-dimensional Kleinian groups and their contrast with the discrete groups of isometry of ?..

Chern Character for Twisted ComplexesWe construct the Chern character from the .-theory of twisted perfect complexes of an algebroid stack to the negative cyclic homology of the algebra of twisted matrices associated to the stack.
