Abstract

We obtain upper bounds for the multiplicity of an isolated solution of a system of equations f1=...=fM=0f_1=...= f_M =0 in MM variables, where the set of polynomials (f1,...,fM)(f_1,..., f_M) is a tuple of general position in a subvariety of a given codimension which does not exceed MM, in the space of tuples of polynomials. It is proved that for MM\to\infty that multiplicity grows not faster than Mexp[ωM]\sqrt{M}\exp[\omega\sqrt{M}], where ω>0\omega>0 is a certain constant.
