Invariants of generalized tensor fields on a line are classified 
using special polynomials P_mk^(-1/lambda) introduced here 
for this purpose. 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.
