A Computational Solution to a Question by Beauville on the Invariants of the Binary Quintic
Abdelmalek Abdesselam
We obtain an alternate proof of an injectivity result by Beauville for a map from the moduli space of quartic del Pezzo surfaces to the set of conjugacy classes of certain subgroup…

On the Wronskian combinants of binary forms
Abdelmalek Abdesselam, Jaydeep Chipalkatti
For generic binary forms of order we construct a class of combinants $C = \{\C_q: 0 \le q \le r, q \neq 1\}$, to be called the Wronskian combinants of the .…

The bipartite Brill-Gordan locus and angular momentum
Abdelmalek Abdesselam, Jaydeep Chipalkatti
This paper is a sequel to math.AG/0411110. Let P denote the projective space of degree d forms in n+1 variables. Let e denote an integer < d/2, and consider the subvariety X of for…
