Measured Quantum Groupoids Associated with Matched Pairs of Locally Compact Groupoids
arXiv:0906.5247
Abstract
Generalizing the notion of matched pair of groups, we define and study matched pairs of locally compact groupoids endowed with Haar systems, in order to give new examples of measured quantum groupoids.
In this new version paragraph 4.3 has been modified and completed in order to correct a previous technical error which does not really affect our main result
