Fuchsian differential equations of order 3,...,6 with three singular points and an accessory parameter III, Higher order versions of the Dotsenko-Fateev equation

Abstract: For the three Fuchsian differential equations of order 4, 5 and 6, connected with the Dotsenko-Fateev equation of order 3, via addition and middle convolution, we find shift operators and reducibility conditions, and study reducible cases.
