Abstract
We investigate the surface tension between coexisting phases of general discrete lattice systems. In particular the different phases need not be connected by any symmetry. We prove the positivity of the surface tension in the low-temperature regime where the Pirogov-Sinai theory of first-order phase transitions is valid: finite-range Hamiltonian having a finite number of periodic ground states. We give a brief description (with some extensions) of this theory.
