Second-order complex linear differential equations with special functions or extremal functions as coefficients

The classical problem of finding conditions on the entire coefficients A(z) and B(z) guaranteeing that all nontrivial solutions of $f''+A(z)f'+B(z)f=0$ are of infinite order is discussed. Two distinct approaches are used. In the first approach the coefficient A(z) itself is a...
