Critical line (thermodynamics) — In thermodynamics, a critical line is the higher dimensional equivalent of a critical point [1]. It is the locus of contiguous critical points in a phase diagram. These lines cannot occur for a single substance due to the phase rule, but they can … Wikipedia
Non-critical string theory: Lorentz invariance — Usually non critical string theory is considered in frames of the approach proposed by Polyakov [1]. The other approach has been developed in [2] [3] [4]. It represents a universal method to maintain explicit Lorentz invariance in any quantum… … Wikipedia
