Query: Algebraic hypersurfaces   We give an introduction to the study of algebraic hypersurfaces, focusing on
the problem of when two hypersurfaces are isomorphic or close to being
isomorphic. Working with hypersurfaces and emphasizing examples makes it
possible to discuss these questions without any previous knowledge of algebraic
geometry. At the end we formulate the main recent results and state the most
important open questions.
