Necessary conditions


Notes:

First the theorem about necessary conditions for being a digital line. It is not my purpose to explain everything in detail. I only want to show what I have done and what I have used to get the formulation of the theorem. I have to present quite a big number of definitions to be able to write down the formal result. This means that it will probably be not so easy to follow 100% of the time. Do not worry.
