The $\phi$-order of solutions of linear differential equations in the unit disc

In this paper, some results on the $\phi$-order of solutions of linear differential equations with coefficients in the unit disc are obtained. These results yield a sharp lower bound for the sums of $\phi$-order of functions in the solution bases. The results we obtain are a generalization of a rece...

Description
Summary:In this paper, some results on the $\phi$-order of solutions of linear differential equations with coefficients in the unit disc are obtained. These results yield a sharp lower bound for the sums of $\phi$-order of functions in the solution bases. The results we obtain are a generalization of a recent result due to I. Chyzhykov, J. Heittokangas and J. Rättyä.
