A fast algorithmic way to calculate the degree growth of birational mappings
Basil Grammaticos, Alfred Ramani, Adrian Stefan Carstea +1
We present an algorithmic method for the calculation of the degrees of the iterates of birational mappings, based on Halburd's method for obtaining the degrees from the singularity…

On the singularities of the discrete Korteweg-deVries equation
Doyong Um, Alfred Ramani, Basil Grammaticos +2
We study the structure of singularities in the discrete Korteweg-deVries (d-KdV) equation. Four different types of singularities are identified. The first type corresponds to local…
