This work has been supported by the DGICYT (PB91-0378).The free energy of classical two-dimensional solids with repulsive inverse-power interactions is obtained from a recently introduced perturbation theory. We obtain very accurate results for the thermodynamics of the solid phase as compared to the available simulation data.engPerturbation theory for the free energy of classical two-dimensional solids with repulsive inverse-power interactionsjournal articlehttp://dx.doi.org/10.1103/PhysRevB.49.16028http://prb.aps.org/open access536Monte-Carlo simulationThermodynamic propertiesTwo dimensionsHard-sphereTransitionLiquidSystemsFluidTermodinámica2213 Termodinámica
