The Braided Heisenberg Group
We compute the braided groups and braided matrices for the solution
of the Yang-Baxter equation associated to the quantum Heisenberg group. We
also show that a particular extension of the quantum Heisenberg group is dual
to the Heisenberg universal enveloping algebra , and use this result
to derive an action of on the braided groups. We then demonstrate
the various covariance properties using the braided Heisenberg group as an
explicit example. In addition, the braided Heisenberg group is found to be
self-dual. Finally, we discuss a physical application to a system of n braided
harmonic oscillators. An isomorphism is found between the n-fold braided and
unbraided tensor products, and the usual `free' time evolution is shown to be
equivalent to an action of a primitive generator of on the braided
tensor product.Comment: 33 page
Action Research For Information Systems
This tutorial provides an introduction and “how-to” overview of the action research methodology within the context of information technology and qualitative information systems research. The introductory material will deal with conflicting definitions of action research and the appropriate application of this technique in particular information technology settings. The how-to overview will focus on the participatory and clinical forms of action research. The practical overview will conclude with a discussion of criteria for evaluating the effectiveness of action research and the relationship between action research and consulting
