On the limits of real-valued functions in sets involving $ψ$ -density, and applications

J. Heittokangas, Z. Latreuch, J. Wang +1

We prove new results on upper and lower limits of real-valued functions by means of $ψ$ -densities introduced by P. D. Barry in 1962. This allows us to improve several existing resu…

On Petrenko's deviations and second order differential equations

J. Heittokangas, M. A. Zemirni

New results on the oscillation of solutions of $f^{''} + A (z) f = 0$ and on the growth of solutions of $f^{''} + A (z) f^{'} + B (z) f = 0$ are obtained, where $A$ and $B$ are entire functions. Petrenko's…
