Invertible harmonic mappings, beyond Kneser [PDF]
, 2009 We prove necessary and sufficient criteria of invertibility for planarharmonic mappings which generalize a classical result of H. Kneser, also knownas the Rad ́o–Kneser–Choquet theorem.

A note on asymptotics and nonoscillation of linear $q$-difference equations
Electronic Journal of Qualitative Theory of Differential Equations, 2012 We study the linear second order $q$-difference equation $y(q^2t)+a(t)y(qt)+b(t)y(t)=0$ on the $q$-uniform lattice $\{q^k:k\in\mathbb{N}_0\}$ with $q>1$, where $b(t)\ne0$. We establish various conditions guaranteeing the existence of solutions satisfying
