If we specialize algebraic equations having good
properties, we usually face degeneracies. Starting with a bad
specialization, we can try to improve it , performing modifications
under control. If we succeed to get a new specialization with the
initial good properties preserved,we get a permanence statement.
We shall present examples of permanence with particular interest
concerning semi-stable models.
