The Alexander-Hirschowitz theorem describes when a collection of double points in projective space imposes independent conditions on the homogeneous polynomials defining hypersurfaces of a given dimension, generalizing classical polynomial interpolation in several variables to points with higher multiplicities. The theorem gives a complete answer along with a short, known list of exceptional cases where the expected count of independent conditions fails to hold.
