# KP Solitons are Bispectral

@article{Kasman1998KPSA, title={KP Solitons are Bispectral}, author={Alex M Kasman}, journal={arXiv: Mathematical Physics}, year={1998} }

It is by now well known that the wave functions of rational solutions to the KP hierarchy which can be achieved as limits of the pure $n$-soliton solutions satisfy an eigenvalue equation for ordinary differential operators in the spectral parameter. This property is known as ``bispectrality'' and has proved to be both interesting and useful. In a recent preprint (math-ph/9806001) evidence was presented to support the conjecture that all KP solitons (including their rational degenerations) are…
