Theory and Phenomenology of Mixed Amphiphilic Aggregates
  We give a short overview of existing approaches describing shapes and energetics of amphiphilic aggregates. In particular, we consider recent experimental data and theory in relation to mixed aggregates. We point out the outstanding questions deserving further investigations such as stability of single-component vesicles and size growth of mixed vesicles induced by micelle-forming surfactants.
