Query: Non-existence of Global Solutions for a Generalized Fractional
  Differential Problem   Aim of this paper is to study the non-existence of global solutions of the
fractional differential problem involving generalized Katugampola derivative.
We utilize the test function method and fractional integration by parts formula
to obtain the result. An illustrative example is also given.
