TL;DR: In this article, the authors present a new formulation of the tensionless string (T = 0) where the space-time conformal symmetry is manifest using a Hamiltonian BRST scheme and find that it has critical dimension D = 2.

TL;DR: In this article, the nonlinear multiplet model was reformulated as a gauge multiplet and its dynamics were discussed using a nonlinear "duality" that appears to relate the model to a conventional σ-model.

TL;DR: In this article, the authors used the dual description proposed by Seiberg to calculate the pressure in the low temperature confined phase of supersymmetric QCD using perturbation theory to O(g^3_m), where g_m is the gauge coupling in the dual theory.
Abstract: We use the dual description proposed by Seiberg to calculate the pressure in the low temperature confined phase of $N=1$ supersymmetric QCD using perturbation theory to $O(g^3_m)$, where $g_m$ is the gauge coupling in the dual theory. Combining this result with the usual high temperature expansion based on asymptotic freedom, we study how the physics in the intermediate temperature regime depends on the relative size of the scale parameters in the two descriptions. In particular we explore the possibility of having a temperature range where both perturbation expansions are valid.

TL;DR: It seems that it is only possible to generate rotating solutions from non-rotating ones for the special cases when the dilaton coupling parameter $a=0, \pm \sqrt{3}$.
Abstract: We consider the axially symmetric coupled system of gravitation, electromagnetism and a dilaton field. Reducing from four to three dimensions, the system is described by gravity coupled to a non-linear $\sigma$-model. We find the target space isometries and use them to generate new solutions. It seems that it is only possible to generate rotating solutions from non-rotating ones for the special cases when the dilaton coupling parameter $a=0, \pm \sqrt{3}$. For those particular values, the target space symmetry is enlarged.
