Irregular finite order solutions of complex LDE's in unit disc
Igor Chyzhykov, Petro Filevych, Janne Gröhn +2
It is shown that the order and the lower order of growth are equal for all non-trivial solutions of if and only if the coefficient is analytic in the unit disc…
Oscillation of solutions of LDE's in domains conformally equivalent to unit disc
Igor Chyzhykov, Janne Gröhn, Janne Heittokangas +1
Oscillation of solutions of is studied in domains conformally equivalent to the unit disc. The results are applied, for e…
Description of growth and oscillation of solutions of complex LDE's
Igor Chyzhykov, Janne Gröhn, Janne Heittokangas +1
It is known that, equally well in the unit disc as in the whole complex plane, the growth of the analytic coefficients of \begin{equation*} f^{(k)} + A_{k-2} f…
Mean growth and geometric zero distribution of solutions of linear differential equations
Janne Gröhn, Artur Nicolau, Jouni Rättyä
The aim of this paper is to consider certain conditions on the coefficient of the differential equation in the unit disc, which place all normal solutions to the…
