Optimal Regularity of Constant Graphs in Hyperbolic Space

الأصل · EN

Inspired by [6, 7], we study the boundary regularity of constant curvature hypersurfaces in the hyperbolic space Hⁿ⁺¹, which have prescribed asymptotic boundary at infinity. Through constructing the boundary expansions of the solutions, we derive the optimal regularity of the solutions. Moreover, we obtain an equivalent condition that guarantees the smoothness of the solutions.
