A Reciprocal Transformation for the Constant Astigmatism Equation
We introduce a nonlocal transformation to generate exact solutions of the constant astigmatism equation zyy + (1/z)xx + 2 = 0. The transformation is related to the special case of the famous Bäcklund transformation of the sine-Gordon equation with the Bäcklund parameter λ = ±1. It is also a nonlocal symmetry.
متن کاملExact 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.
متن کاملOn 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...
متن کاملAn 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. PACS numbers: 04.20-q, 04.20.Dw, 04.20.Jb, 04.25-g
متن کاملNew exact solutions of the mBBM equation
The enhanced modified simple equation method presented in this article is applied to construct the exact solutions of modified Benjamin -Bona -Mahoney equation. Some new exact solutions are derived by using this method. When some parameters are taken as special values, the solitary wave solutions can be got from the exact solutions. It is shown that the method introduced in this paper has gener...
