Singularity of generalized grey Brownian motions with different   parameters
  In this note we prove that the probability measures generated by two generalized grey Brownian motions with different parameters are singular with respect to each other. This result can be interpreted as an extension of the Feldman-H\'ajek dichotomy of Gaussian measures to a family of non-Gaussian measures
