Exact Solution of Biswas-milovic Equation Using New Efficient Method

Biswas and Milovic proposed a generalized model for the NLSE that accounts for several imperfections in the fiber during long distance transmission of these pulses. This paper studies the exact solution of the BiswasMilovic equation with Kerr law nonlinearity by a new efficient method. The results reveal that the method is explicit, effective, and easy to use.

On Fuzzy Solution for Exact Second Order Fuzzy Differential Equation

In the present paper, the analytical solution for an exact second order fuzzy initial value problem under generalized Hukuhara differentiability is obtained. First the solution of first order linear fuzzy differential equation under generalized Hukuhara differentiability is investigated using integration factor methods in two cases. The second based on the type of generalized Hukuhara different...

An Exact Solution of the Einstein’s Equation

In this short letter we present a rigorous vacuum solution of the Einstein’s equation with a few singular surfaces. In contrast with the well known solutions, this solution looks somewhat exotic and strange. The physical meanings of the parameters and coordinates are still absent.

Exact Solution of Schrödinger equation with deformed Ring-Shaped Potential

Exact solution of the Schrödinger equation with deformed ring shaped potential is obtained in the parabolic and spherical coordinates. The Nikiforov-Uvarov method is used in the solution. Eigenfunctions and corresponding energy eigenvalues are calculated analytically. The agreement of our results is good. PACS numbers: 03.65.-w, 12.39.Jh, 21.10.-k
