Abstrakt: Consider a compact surface of genus |$\geq 2$| equipped with a metric that is flat everywhere except at finitely many cone points with angles greater than |$2\pi $|⁠. Following the technique in the work of Burns, Climenhaga, Fisher, and Thompson, we prove that sufficiently regular potential functions have unique equilibrium states if the singular set does not support the full pressure. Moreover, we show that the pressure gap holds for any potential that is locally constant on a neighborhood of the singular set. Finally, we establish that the corresponding equilibrium states have the |$K$| -property and closed regular geodesics equidistribute. [ABSTRACT FROM AUTHOR]
