This inspiring paper examines three approaches to proving optimal bounds for anisotropic composites made by mixing two isotropic conducting materials in specified proportions. These bounds are achieved via: the compensated compactness method, the representation formulas and the Hashin-Shtrikman variational principles. Each of these methods is lucidly presented, including their comparison.
