Prospects for a Measurement of $\alpha_s$ via Scaling Violations of   Fragmentation Functions in Deeply Inelastic Scattering
  The prospects for a determination of the strong coupling constant $\alpha_s$ via scaling violations of fragmentation functions in deeply inelastic scattering are studied. The statistical error in the case of an integrated luminosity of $250 pb^{-1}$, and the theoretical errors due to the various parton density parametrizations and to the factorization scale dependence are estimated.
