Wakimoto to head NSF geosciences directorate

Engineering Directorate

There are currently several digital HDTVproposals being evaluated by the FCC. There areseveral advantages to the acceptance of a digital HDTVstandard. The technical advantages, which will be ofmost concern to NASA is the fact that the use of digitaltechnology increases the inter-operability of thesesystems. The output of a digital system can berelatively easily i...

Integrable Hierarchies and Wakimoto Realization

In our papers [20, 21] we proposed a new approach to integrable hierarchies of soliton equations and their quantum deformations. We have applied this approach to the Toda field theories and the generalized KdV and modified KdV (mKdV) hierarchies. In this paper we apply our approach to the Ablowitz-Kaup-Newell-Segur (AKNS) hierarchy [1] and its generalizations. In particular, we show that the fr...

Geoinformatics: Transforming data to knowledge for geosciences

An integrative view of Earth as a system, based on multidisciplinary data, has become one of the most compelling reasons for research and education in the geosciences. It is now necessary to establish a modern infrastructure that can support the transformation of data to knowledge. Such an information infrastructure for geosciences is contained within the emerging science of geoinformatics, whi...

Deformation of the Wakimoto construction

We present the extension of the Wakimoto construction to the su(2)k quantum current algebra and its associated Zk quantum parafermion algebra. This construction is achieved in terms of various deformations of three classical free boson fields. We also give the vertex operators corresponding to the quantum spin-j representation.
