Towards a phase diagram of the 2D Skyrme model

We discuss calculations of the phase diagram of the baby Skyrme model, a tw o-dimensional version of the model that has been so successful in the descr iption of baryons. Contact is made with the sine-Gordon model in 1D, and re lations with the Skyrme model used in the quantum-Hall effect are pointed o ut. It is shown that at finite temperature the phase diagram is dominated b y a liquid, and not by the crystal that plays a role for zero temperature.
