Oscillation of fixed points of solutions and their derivatives of some higher linear differential equations. (English) Zbl 1299.34280
Summary: We investigate the relationship between solutions and their derivatives for the differential equation $f^{(k)}+A_{k-1}f^{(k-1)}+\dots +A^0f=0$ with $$k\geq 2$$ and entire functions of finite iterated $$p$$-order, when $$A_j\;(j=0,1,\dots ,k-1)$$ are entire functions of finite iterated $$p$$-order in order to generalize and extend the results given by Wang and Lü, Liu and Zhang and Belaïdi.
