Resumen:
Sparsemixed discriminants characterize those polynomial systems with fixed supports,which define a singular variety. We will discuss the relation between sparsemixed discriminants and the resultant of the given polynomials and their toricjacobian, which yields a multiplicativity formula for sparse mixeddiscriminants. We will also discuss conditions for mixed discriminants to becomputed via iterated discriminants, with possible extra factors coming fromthe singularities of the discriminantal locus.
