Comment on "Fluctuation-Driven First-Order Transition in Pauli-Limited   $d$-Wave Superconductors"
  This is a Comment on a recent Letter (Phys.Rev.Lett.93, 247002 (2004)) written by Dalidovich and Yang. It is pointed out that any Pauli-limited approach neglecting the vortices is inapplicable to describing the FFLO state in CeCoIn5.
