Query: Logarithmic A-hypergeometric series   The method of Frobenius is a standard technique to construct series solutions
of an ordinary linear differential equation around a regular singular point. In
the classical case, when the roots of the indicial polynomial are separated by
an integer, logarithmic solutions can be constructed by means of perturbation
of a root.
  The method for a regular A-hypergeometric system is a theme of the book by
Saito, Sturmfels, and Takayama. Whereas they perturbed a parameter vector to
obtain logarithmic A-hypergeometric series solutions, we adopt a different
perturbation in this paper.
