On Transcendental Meromorphic Solutions of One Type of Nonlinear Differential Equations

Abstract: This study employed Nevanlinna theory to examine finite-order meromorphic solutions of nonlinear differential equations with the form $f^n+a{f}^{n-2}{f}^{″}+P_d\left(z,f\right)=p_1\left(z\right){\text{e}}^{a_1\left(z\right)}+p_2\left(z\right){\text{e}}^{a_2\left(z\right)}+p_3\left(z\right){\text{e}}^{a_3\left(z\right)}$ Where $P_d\left(z,f\right)$ is polynomial of degree $d$ , $p_i\left(i=1,2,3\right)$ are non-zero constants, and $a_i\left(z\right)\left(i=1,2,3\right)$ are distinct non-constant polynomials. Corresponding examples are provided for illustration.
