Existence and uniqueness of a positive solution to generalized nonlocal   thermistor problems with fractional-order derivatives
  In this work we study a generalized nonlocal thermistor problem with fractional-order Riemann-Liouville derivative. Making use of fixed-point theory, we obtain existence and uniqueness of a positive solution.
