Title:
Braided Quantum E(2) Groups and Contraction

Quantum E(2) groups for real deformation parameters $q$ studied by S. L. Woronowicz produced new examples of locally compact quantum groups. However, for complex values of the deformation parameter $q$ there are technical difficulties which prevent it from being a locally compact quantum group. In this talk we will construct a braided multiplicative unitary $W$ which generates the braided version of quantum E(2). We will also briefly talk about the contraction procedure coupling the comultiplications of braided quantum SU(2) and braided quantum E(2) groups.
