Real root finding for low rank linear matrices
Didier Henrion, Simone Naldi, Mohab Safey El Din
We consider matrices (with ) in a real affine subspace of dimension . The problem of finding elements of low rank in such spaces finds many applications in…

Real root finding for rank defects in linear Hankel matrices
Didier Henrion, Simone Naldi, Mohab Safey El Din
Let be matrices with entries in $\QQ$ and Hankel structure, i.e. constant skew diagonals. We consider the linear Hankel matrix $H(\vecx)=H\_0+\X\_1H\…
