Inverting catalecticants of ternary quartics

Autor: Moncusí, Laura Brustenga i, Cazzador, Elisa, Homs, Roser

We study the reciprocal variety to the linear space of symmetric matrices (LSSM) of catalecticant matrices associated with ternary quartics. With numerical tools, we obtain 85 to be its degree and 36 to be the ML-degree of the LSSM. We provide a geom
