In this talk, we present some details of how to implement the consistency scheme for 5-point lattice equations broadly introduced in the talk by Wolfgang Schief. We will also present some other formulations of consistency for 5-point lattice equations, particularly for equations in a hexagonal lattice. Time permitting we will also present consistent multicomponent 5-point equations and consisten ... More

Consistency of discrete equations on higher dimensional lattices constitutes a central element of integrable systems theory. The consistency of discrete equations defined on the squares and cubes of lattices of type B and the octahedra of lattices of type A have been studied extensively and with great success. However, it appears that the consistency of discrete equations naturally defined on latt ... More

There is Hesse's principle of transfer: the transfer of geometric assertions from one dimension into another, facilitated by the fact that the projective subgroup stabilising a normal curve is isomorphic in every dimension. When space is coordinatised via a normal curve, geometric assertions become SL2-invariant equations, as opposed to homogeneous equations if a simplex is used. Although examples ... More
