Moreover, we obtain that every bordered Riemann surface admits an almost proper CMC-1 face into de Sitter 3-space S31, and we show that on every compact Riemann surface M, there is a Cantor set C ⊂ M such that M\C admits an almost proper CMC-1 face into S31. These results follow from different uniform approximation theorems for holomorphic null curves in C2 × C* that we also establish in this paper.}, organization = {Grant PID2021-124157NB-I00 funded by MCIN/AEI/10.13039/501100011033/‘ERDF A way of making Europe’, Spain; and by Comunidad Autónoma de la Región de Murcia, Spain, within the framework of the Regional Programme in Promotion of the Scientific and Technical Research (Action Plan 2022)}, organization = {Fundación Séneca, Regional Agency of Science and Technology, REF, 21899/PI/22}, organization = {State Research Agency (AEI) via the Grants no.
