"  An introduction to apolarity: how to solve a cubic equation using linear algebra "
  Fulvio Gesmundo  


The notion of apolarity is widely used in classical algebraic geometry and invariant theory. After briefly introducing the subject and the notion of apolar ideal of a homogeneous form, I present a motivating example in which apolarity is used to determine the roots of a generic univariate polynomial of degree 3.
