Real forms of algebraic varieties

Abstract: A real form of a complex projective variety $X$ is a scheme over $\mathbb{R}$ whose complexification is $\mathbb{C}$-isomorphic to $X$. A natural question "does a given variety have finitely many nonequivalent real forms?" turns out to be quite difficult even in dimension 2. I will review some known results on this topic.
