We show that the rectification of skew Young tableaux is characterized as a
recurrence formula of tropical matrices. This can be regarded as a Lax
formulation of the ultradiscrete (tropical) KP equation. The proof is based on
the results of Mikami...

In this paper, we consider the Perron theorem over the real Puiseux field. We
introduce a recursive method for calculating Perron roots and Perron vectors of
positive Puiseux matrices (which satisfy some condition of genericness) by
means of combi...

The (M,K)-reduced non-autonomous discrete KP equation is linearised on the
Picard group of an algebraic curve. As an application, we construct theta
function solutions to the initial value problem of some special discrete KP
