Rigorous Probabilistic Analysis of Equilibrium Crystal Shapes T. Bodineau, D. Ioffe and Y. Velenik J. Math. Phys. 41, 1033-1098 (2000). The rigorous microscopic theory of equilibrium crystal shapes has made enormous progress during the last decade. We review here the main results which have been obtained, both in two and higher dimensions. In particular, we describe how the phenomenological Wulff and Winterbottom constructions can be derived from the microscopic description provided by the equilibrium statistical mechanics of lattice gases. We focus on the main conceptual issues and describe the central ideas of the existing approaches. Key words: Equilibrium crystal shapes, Wulff construction, Winterbottom construction.
