On solutions of differential equations with ``common zero'' at infinity

Árpád Elbert, Jaromír Vosmanský (1997)

Archivum Mathematicum

The zeros $c_{k} (ν)$ of the solution $z (t, ν)$ of the differential equation $z^{''} + q (t, ν) z = 0$ are investigated when $lim_{t \to \infty} q (t, ν) = 1$ , $\int^{\infty} | q (t, ν) - 1 | d t < \infty$ and $q (t, ν)$ has some monotonicity properties as $t \to \infty$ . The notion $c_{κ} (ν)$ is introduced also for $κ$ real, too. We are particularly interested in solutions $z (t, ν)$ which are “close" to the functions $sin t$ , $cos t$ when $t$ is large. We derive a formula for $d c_{κ} (ν) / d ν$ and apply the result to Bessel differential equation, where we introduce new pair of linearly independent solutions replacing the usual pair $J_{ν} (t)$ , $Y_{ν} (t)$ . We show the concavity of $c_{κ} (ν)$ for $| ν | \geq \frac{1}{2}$ and also...
