• ON SOME SUMMATION-DIFFERENCE INEQUALITIES

Dr. K. L. Bondar*

Abstract


In this paper we shall consider the equation

f (t, ∆x(t), x(t), Fx(t)) = 0; x(0)) =x0

where f : J × R3 → R and F be an operator from J → R into J → R. We also discuss about over and under function of above equation and its δ- approximate solution.

Keywords


Difference Equation, Summation equation, Summation inequality, Under and over Function.
