Some results on transcendental entire solutions of certain nonlinear differential-difference equations

In this paper, we study the transcendental entire solutions for the nonlinear differential-difference equations of the forms: $f^{2}(z)+\widetilde{\omega} f(z)f’(z)+q(z)e^{Q(z)}f(z+c)=u(z)e^{v(z)}$,and$f^{n}(z)+\omega f^{n-1}(z)f’(z)+q(z)e^{Q(z)}f(z+c)=p_{1}e^{\lambda_{1} z}+p_{2}e^{\lambda_{2} z}, \quad n\geq 3,$where$\omega$isaconstant,$\widetilde{\omega}, c, \lambda_{1}, \lambda_{2}, p_{1}, p_{2}$arenon-zeroconstants,$q, Q, u, v$arepolynomialssuchthat$Q,v$arenotconstantsand$q,u\not\equiv0$. Our results are improvements and complements of some previous results.
