Abstract: | The relation between solutions of second order linear differential equations with periodic coefficients$f^{\prime\prime}+P_1(e^{z})+P_2(e^{-z})]f^{\prime}+Q_1(e^{z})+Q_2(e^{-z})]f=0$ and $f^{\prime\prime}+P_1(e^{z})+P_2(e^{-z})]f^{\prime}+Q_1(e^{z})+Q_2(e^{-z})]f=R_1(e^{z})+R_2(e^{-z})$,their 1th derivatives, their second derivatives, their differential polynomials with functions of small growth is investigated, where $P_j(z),~
Q_j(z),R_j(z)$(j=1,2) are polynomials. |
