  The Wro\'nski determinant ({\em Wro\'nskian}), usually introduced in standard
courses in Ordinary Differential Equations (ODE), is a very useful tool in
algebraic geometry to detect ramification loci of linear systems. The present
survey aims to describe some "materializations" of the Wro\'nskian and of its
close relatives, {\it the generalized Wro\'nskians}, in algebraic geometry.
Emphasis will be put on the relationships between Schubert Calculus and Linear
Ordinary Differential Equations.}
