F or solutions second order elliptic equations critical zero sets represen t the singular parts of sets. They ha v e Haus-dor dimension not greater than n 2. Hence sometimes they are called the singular sets of solutions. This result is not true for higher order elliptic equa-tions. F or example the critical zero sets ma y o ...

Take the survey WebCubic equations (where each term has combined degree at most three) such as \(Y^2 + X Y = X^3 + 1\) are where things are most interesting: increase the degree and things get really hard; decrease the degree and the results are trivial. The term "elliptic curves" refers to the study of these equations.
