Multi-Component Matrix KP Hierarchies as Symmetry-Enhanced Scalar KP Hierarchies and Their Darboux-B"acklund Solutions
Henrik Aratyn, Emil Nissimov, Svetlana Pacheva
We show that any multi-component matrix KP hierarchy is equivalent to the standard one-component (scalar) KP hierarchy endowed with a special infinite set of abelian additional sym…

Composite Vector and Tensor Gauge Fields, and Volume-Preserving Diffeomorphisms
Eduardo I. Guendelman, Emil Nissimov, Svetlana Pacheva
We describe new theories of composite vector and tensor (p-form) gauge fields made out of zero-dimensional constituent scalar fields (``primitives''). The local gauge symmetry is r…
