Pocket set theory

In the mathematical field of differential geometry a Liouville surface is a type of surface which in local coordinates may be written as a graph in R³

$z=f(x,y)$

such that the first fundamental form is of the form

$ds^{2}=(f_{1}(x)+f_{2}(y))(dx^{2}+dy^{2}).\,$

Sometimes a metric of this form is called a Liouville metric. Every surface of revolution is a Liouville surface.
