On two curvature-driven problems in Riemann–Finsler geometry

<!-- *** Custom HTML *** --> This article uses the Berwald connection exclusively, together with its two curvatures, to cut an efficient path across the landscape of Finsler geometry. Its goal is to initiate differential geometers into two key research areas in the field: the search for unblemished "unicorns" and the study of Ricci flow. The exposition is almost self-contained.
