Query: On the absence of global weak solutions for a nonlinear time-fractional
  Schr\"odinger equation   In this paper, an initial value problem for a nonlinear time-fractional
Schr\"odinger equation with a singular logarithmic potential term is
investigated. The considered problem involves the left/forward Hadamard-Caputo
fractional derivative with respect to the time variable. Using the test
function method with a judicious choice of the test function, we obtain
sufficient criteria for the absence of global weak solutions.
