The Haar measure on some locally compact quantum groups
A locally compact quantum group is a pair (A,Φ) of a C-algebra A and a -homomorphism Φ from A to the multiplier algebra M(A ⊗ A) of the minimal C-tensor product A ⊗ A satisfying certain assumptions (see [K-V1] and [K-V2]). One of the assumptions is the existence of the Haar weights. These are densely defined, lower semi-continuous faithful KMS-weights satisfying the correct invariance propertie...
متن کاملA Property of the Haar Measure of Some Special LCA Groups
The Euclidean group (Rn,+) where (n?N, plays a key role in harmonic analysis. If we consider the Lebesgue measure ()nd?xR as the Haar measure of this group then 12(2)()nd?x=d?RR. In this article we look for LCA groups K, whose Haar measures have a similar property. In fact we will show that for some LCA groups K with the Haar measure K?, there exists a constant such that 0KC>()(2)KKK?A=C?A for ...
متن کاملMotivic Haar Measure on Reductive Groups
We define a motivic analogue of the Haar measure for groups of the form G(k((t))), where k is an algebraically closed field of characteristic zero, and G is a reductive algebraic group defined over k. A classical Haar measure on such groups does not exist since they are not locally compact. We use the theory of motivic integration introduced by M. Kontsevich to define an additive function on a ...
متن کاملHaar Weight on Some Quantum Groups
We present a number of examples of locally compact quantum groups. These are quantum deformations of the group of affine transformations R (‘ax+b’ group) and C (Gz group). Starting from a modular multiplicative unitary W we find (under certain technical assumption) a simple formula expressing the (right) Haar weight on the quantum group associated with W . The formula works for quantum ‘ax + b’...
متن کاملHaar Measure for Compact Right Topological Groups
Compact right topological groups arise in topological dynamics and in other settings. Following H. Furstenberg's seminal work on distal flows, R. Ellis and I. Namioka have shown that the compact right topological groups of dynamical type always admit a probability measure invariant under the continuous left translations; however, this invariance property is insufficient to identify a unique pro...
