Calculating algebraic entropies: an express method
Alfred Ramani, Basil Grammaticos, Ralph Willox +1
We describe a method for investigating the integrable character of a given three-point mapping, provided that the mapping has confined singularities. Our method, dubbed "express",…
Coprimeness-preserving non-integrable extension to the two-dimensional discrete Toda lattice equation
Ryo Kamiya, Masataka Kanki, Takafumi Mase +1
We introduce a so-called `coprimeness-preserving non-integrable' extension (another terminology is `quasi-integrable' extension) to the two-dimensional Toda lattice equation. We be…
Full-deautonomisation of a lattice equation
Ralph Willox, Takafumi Mase, Alfred Ramani +1
In this letter we report on the unexpected possibility of applying the full-deautonomisation approach we recently proposed for predicting the algebraic entropy of second-order bira…
