Abstract
Based on the principal representation of toroidal Lie algebra , we construct a high–dimensional integrable hierarchy of Hirota bilinear equation. This hierarchy is in fact the D extension of type Drinfeld–Sokolov hierarchy. Furthermore, we also study the Darboux transformations of type Drinfeld–Sokolov and its extension by virtue of two-component neutral free fermions.
期刊介绍:
The Journal of Geometry and Physics is an International Journal in Mathematical Physics. The Journal stimulates the interaction between geometry and physics by publishing primary research, feature and review articles which are of common interest to practitioners in both fields.
The Journal of Geometry and Physics now also accepts Letters, allowing for rapid dissemination of outstanding results in the field of geometry and physics. Letters should not exceed a maximum of five printed journal pages (or contain a maximum of 5000 words) and should contain novel, cutting edge results that are of broad interest to the mathematical physics community. Only Letters which are expected to make a significant addition to the literature in the field will be considered.
The Journal covers the following areas of research:
Methods of:
• Algebraic and Differential Topology
• Algebraic Geometry
