| Abstract: | Some of the most fundamental properties of PDEs are expressed as conservation laws; the same is true for partial difference equations. A fundamental question is the following: when are two conservation laws essentially different? For PDEs the answer is found by calculating a function called the characteristic however, until now, no such characteristic has been known for partial difference equations. This talk describes the problem, our search for a characteristic and the surprisingly simple solution. The talk will be accessible to a general applied maths audience; no specialist knowledge is assumed.
