Sažetak
Love's bounding inequalities for Laguerre functions $L_\nu^\mu(x)$ are significantly improved by two different methods in the real domain. The first method takes Luke's exponential inequalities for the confluent hypergeometric $\Phi \equiv \, _1F_1$, while the second approach explores the upper bounds for the first kind Bessel function $J_\mu(x)$ by Landau, and Olenko's now-a-days derived bound for the same special function. Finally, we deduce a bounding function for $L_\nu^\mu(x)$ combining Krasikov's uniform bound for Bessel functions with Olenko's result.
