Abstract: We study the existence of a global meromorphic fundamental system of solutions for a system of two differential equations $ E_{x} = (az +q(x))E$, where $ a$ is a constant diagonal matrix, and $ q(x)$ is an off-diagonal meromorphic function, for each $ z \in \mathbb{C}$. Following Gesztesy and Weikard (1998), who investigated this property of functions $ q(x)$ and its connection to finite-gap solutions of soliton equations, we call such $ q(x)$ Picard potentials. We obtain conditions for the Picard property of various potentials $ q(x)$.
