Virtual Compton Scattering--Generalized Polarizabilities of Nucleons and   Pions
  Virtual Compton scattering off nucleons and pions at low energies is discussed.   Predictions for the generalized polarizabilities of the nucleon are presented within the framework of heavy-baryon chiral perturbation theory and the linear sigma model.   First results for the generalized polarizabilities of the charged pion in chiral perturbation theory at ${\cal O}(p^4)$ are shown.
