The Number of Solutions to Some Systems of Equations / Zaitseva A.N. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2010. № 2. P. 47-50 [Moscow Univ. Math. Bulletin. Vol. 72, N 2, 2017. P. 81-84].
An estimate for the number of solutions to multi-homogeneous systems of equations is obtained by using properties of the Hilbert function of multi-homogeneous ideals.
Key words:
number of solutions, multiprojective equations, Hilbert function,
multi-projective space, zero-dimensional ideals.
