Almeida, Ricardo A nonstandard characterization of regular surfaces. (English) Zbl 1130.26025 Balkan J. Geom. Appl. 12, No. 2, 1-7 (2007). Summary: In the present work we approach the study of surfaces using nonstandard analysis, by providing first a nonstandard characterization of a surface. Further, the tangent space to a surface is defined as well.
