Toric varieties from cyclic matrix semigroups
Francesco Galuppi, Mima Stanojkovski
We present and expand some existing results on the Zariski closure of cyclic groups and semigroups of matrices. We show that, with the exclusion of isolated points, their irreducib…

Toric geometry of path signature varieties
Laura Colmenarejo, Francesco Galuppi, Mateusz Michałek
In stochastic analysis, a standard method to study a path is to work with its signature. This is a sequence of tensors of different order that encode information of the path in a c…

On the number of Waring decompositions for a generic polynomial vector
Elena Angelini, Francesco Galuppi, Massimiliano Mella +1
We prove that a general polynomial vector in three homogeneous variables of degrees has a unique Waring decomposition of rank 7. This is the first new c…
