For the case of positive characteristic, a new invariant of formal power series, a width, is defined. Some applications to the geometric quantization of a line and conformal quantum field theory are discussed as well.17 pages, see also http://www.math.upenn.edu/~mihailov/papers.htmlRepresentation TheoryQuantum Algebra17B66, 22E27, 22E65 (Primary) 12E10, 12J10, 81R10 (Secondary)text
