| Abstract: | The authors investigate the growth of solutions to the nonhomogeneous linear differential equation $f^{(k)}+A_{k-1}(z)f^{(k-1)}+cdots+A_{s}(z)f^{(s)}+cdots+A_{0}(z)f=F(z)$, where $A_{j} (j=0,1,cdots,k-1)$ and $F$are entire functions. When the domain coefficient $A_{s}$ grows faster than other coefficients, the precise estimates of the hyper-order of transcendental entire solutions to the previous higher order linear differential equation are obtained. |
