Nabla discrete fractional calculus and nabla inequalities. (English) Zbl 1190.26001
Summary: Here we define a Caputo like discrete nabla fractional difference and we produce discrete nabla fractional Taylor formulae for the first time. We estimate their remainders. Then we derive related discrete nabla fractional Opial, Ostrowski, Poincaré and Sobolev type inequalities.
