A Note on Amenability of Locally Compact Quantum Groups
Printed: Jun 2014
Piotr M. Sołtan,
In this short note we introduce a notion called ``quantum injectivity''
of locally compact quantum groups, and prove that it is equivalent
to amenability of the dual. Particularly, this provides a new characterization
of amenability of locally compact groups.
