Summary
In this preliminary chapter we study the geometry ofsmooth two-dimensional surfaces in $\mathbb{R}^3$ asa “warm-up problem” and we recover some classicalresults. In the fist part of the chapter we considersurfaces in $\mathbb{R}^3$ endowed with the standardEuclidean product. In the second part we studysurfaces in the 3D pseudo-Euclidean space, that is$\mathbb{R}^3$ endowed with a sign-indefinite innerproduct.
