Abstract The paper deals with the problem under which conditions for parameters $$s_1,s_2\in \mathbb R$$ s 1 , 2 ∈ R , $$1\le p,q_1,q_2\le \infty $$ ≤ p</...

This paper considers a new Double Integral transform called Sumudu-Elzaki DSET. The combining of the DSET with semi-analytical method, namely variational iteration method DSETVIM, to arrive numerical solution nonlinear PDEs Fractional Order derivatives. proposed dual property decreases number calculations required, so these two methods leads calculating solution's speed. suggested technique is ...
