in this present work, the kudryashov method and the functional variable method are used to construct exact solutions of the complex kdv equation. the kudryashov method and the functional variable method are powerful methods for obtaining exact solutions of nonlinear evolution equations.

In this paper, we investigate the general solution and the generalized Hyers-Ulam stability of a new functional equation satisfied by $f(x) = x^{24}$, which is called quattuorvigintic functional equation in intuitionistic fuzzy normed spaces by using the fixed point method.These results can be regarded as an important extension of stability results corresponding to functional equations on norme...

the aim of this paper is to show how some measures of noncompactness in the banach space of continuous functions defined on two variables can be applied to the solvability of a general system of functional integral equations . the results obtained generalize and extend several equations . an illustrative example is also presented .

We study Riemann-type functional equations with respect to value-distribution theory and derive implications for their solutions. In particular, a fixed complex number $a\neq0$ function from the Selberg class $\mathcal{L}$, we prove Riemann-von Mangoldt formula of a-points $\Delta$-factor equation $\mathcal{L}$ an analog Landau's over these points. From last that ordinates $a$-points are unifor...
