“…By now various models, e.g. c = −2 model [3,5,6,7], gravitationally dressed CFTs [8,9], WZNW models with fractional k [4,10] and k = 0 [11,12,13,14] have been studied, and a number of applications, including critical polymers [3,15,16], percolation [17,18], quantum Hall effect [19,20], disordered systems [11,12,21,22,23], sandpile model [24], turbulence [25,26,27], MHD [28], D-brane recoil [29,30], etc. have been discussed.…”
