Computing the continuous symmetries of a parametrized variety

Benjamin Biaggi, Jan Draisma, Fulvio Gesmundo +2

We prove that the symmetry Lie algebra of a parametrized variety can be determined directly from the parametrization, without computing the vanishing ideal of the variety. We deriv…

Symmetric subrank and its border analogue

Benjamin Biaggi, Jan Draisma, Koen de Nooij +1

The symmetric subrank of homogeneous polynomial is the largest number of terms in a diagonal form to which it can be specialized by a (typically non-invertible) linear variable sub…
