The Nadirashvili surface is a notable example of a minimal surface, which is a surface that locally minimizes area. More specifically, it is a type of mathematical surface that is defined in terms of its geometric properties and is studied in differential geometry. The Nadirashvili surface is particularly interesting due to its unique characteristics: it is a complete minimal surface that has finitely many singular points, yet it is not embedded, meaning that it intersects itself.
