The technique is among the most powerful approaches currently used to achieveprecise solutions of the partial differential equations that are nonlinear. We systematically show the procedure to obtain the solution which is achieved by developing infinitesimal transformation, prolongations, infinitesimal generatorsand invariant transformations hence symmetry solutions of the fifth order Sawada-Kotera equation.</p> <p><strong><em>Key Words</em></strong>- Lie symmetry analysis.

This logic can then be followed to create a counterexample and a proof for Beal’s conjecture.</p> Halima Jibril Mohamed, Adela Zyfi, Ghedlawit Futzum ##submission.copyrightStatement## Tue, 23 Jul 2019 00:00:00 +0000 Convergence of the Collatz Sequence <p>For any natural number was created the supplement sequence, that is convergent together with the original Collatz sequence. The numerical parameter - index was defined, that is the same for both sequences. This new method provides the following results:</p> <ol> <li>All natural numbers were distributed into six different classes;</li> <li>The properties of index were found for the different classes;</li> <li>For any natural number was constructed the bounded sequence of increasing numbers,</li> </ol> <p>&nbsp;&nbsp;&nbsp; that is convergent together with the regular Collatz sequence.</p> Anatoliy Nikolaychuk ##submission.copyrightStatement## Tue, 23 Jul 2019 00:00:00 +0000 Karp's Theorem in Inverse Obstacle Scattering Problems <p>In this work, we provide a proof of the so-called Karp's theorem in a different approach. We&nbsp;use the unique continuation principle together with the monotonicity of eigenvalues for the&nbsp;negative Laplace operator. This method is new and would be applicable to other types of&nbsp;inverse scattering problems.</p> Jaemin Shin ##submission.copyrightStatement## Wed, 14 Aug 2019 09:22:01 +0000
