Monohedral Tilings of a Convex Disc with a Smooth Boundary

Abstract: In this paper we give a complete description about normal monohedral tilings of a convex disc with smooth boundary where we have at most three topological discs as tiles. This result is a far-reaching generalization of the results of Kurusa, L\'angi and V\'igh \cite{KLV2020}. Some further partial results are proved for non-normal tilings.
