Kodaira fibrations of minimal signature

Abstract: Kodaira fibrations are surfaces of general type with a non-isotrivial fibration, which
are differentiable fibre bundles. They are known to have positive signature divisible
by 4. Examples are known only with signature 16 and more.
We review approaches to construct examples of low signature 4,8,12.
