摘要：
We use the renormalisation-group analysis to study a Landau-Ginzburg-Wilson model of unconventional superconductivity which is generalised to account for intrinsic magnetic fluctuations in zero external magnetic field as well as for disorder of the random-T(c) type. By studying the RG flow equations for the two-point vertices only, we prove that, to first order in the epsilon-expansion, the specific heat at the phase transition point is finite. The proof can be extended to arbitrary quartic anisotropy of the order parameter.
