We study solutions to the Kadomtsev-Petviashvili equation whose underlying algebraic
curves undergo tropical degenerations. Riemann's theta function becomes a finite …

In order to study analogs of objects defined for smooth curves, we may think of a nodal curve
as a smooth curve which is defined over a non-archimedean field K such as Q (ϵ) or the …

Abstract (EN) Physics provides new, tantalizing problems that we solve by developing and
implementing innovative and effective geometric tools in nonlinear algebra. The techniques …
