The Hardy-Littlewood-Pólya (HLP) inequality [1] states that if a∈l~p,b∈l~q and p>1,q>1,1/p + 1/q>1, λ=2-(1/p+1/q),then Σ[(a_rb_s)/︱r-s︱~λ](r≠s)≤C‖a‖
In this article,we apply the concept of hyper-order to higher order linear diffierential equations with periodic coefficients,investigate the existence and the
This article concerns the construction of approximate solutions for a general stochastic integrodifferential equation which is not explicitly solvable and whose
