We derive the jump in the specific heat at T=Tc for a superconductor in a
non-Fermi liquid model.
We took into consideration the two possible limits in this problem:
the spin-charge separation model for a Fermi liquid and the usual non-Fermi
liquid model which satisfies the homogeneity relation for the spectral
function 
, 
).
We also
derive the order parameter behavior for these two cases in the vecinity
of the critical temperature.
