In this paper, the Laplace-Homotopy&nbsp;Analysis Method (LHAM) is applied to obtain approximate analytic solutions of the nonlinear&nbsp;Rosenau-Hyman Korteweg-de Vries (KdV), K(2, 2), and Burgers' equations of fractional order&nbsp;with initial conditions. The solutions of these equations are calculated in the form of convergent&nbsp;series. The solutions obtained converge to the exact solution when α = 1, showing the reliability&nbsp;of LHAM.</p> S.

The fundamental governing dimensionless coupled boundary layer partial differential equations are solved by the method of lines (MOL). Computations are then performed to determine the effects of the governing flow parameters. The results show that an increase in Soret number, Dufour number and Hall current parameter, causes an increase in the primary and secondary velocities of the fluid flow. As rotating parameter increases, the primary velocity of the flow decreases. Similarly, as Dufour and Soret numbers increase, the temperature and concentration profiles of the fluid flow increase. The effects of the flow parameters on primary and secondary velocity, temperature and concentration fields for externally cooling of the plate are shown graphically.</p> M. O. Durojaye, K. A.

As special cases, we give sum formulas of Fibonacci, Lucas, Pell, Pell-Lucas, Jacobsthal, Jacobsthal-Lucas numbers. We present the proofs to indicate how these formulas, in general, were discovered. Of course, all the listed formulas may be proved by induction, but that method of proof gives no clue about their discovery. Our work generalize second order recurrence relations.</p> Yuksel Soykan ##submission.copyrightStatement## http://journalarjom.com/index.php/ARJOM/article/view/30196 Sun, 24 May 2020 00:00:00 +0000
