One of the fit conjectures, which was stated 100 years ago and proved in the 1980's, said that reduced alternating projections of alternating knots have the minimal number of crossings. We prove a generalization of this for knots in S × I, where S is a surface. We use a combination of geometric and polynomial techniques.
