The Braided Heisenberg Group

We compute the braided groups and braided matrices $B(R)$ for the solution $R$ 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 $U_{q}(h)$, and use this result to derive an action of $U_{q}(h)$ 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 $U_{q}(h)$ 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
