Аннотация: The general polynomial with variable coefficients is considered. In terms of the resultants of this polynomials and its derivatives simple rational expressions in the coefficients of the polynomial are found for its multiple zeros. Similar results are extended to systems of n polynomial equations with n unknowns. Justifications of Показать полностьюthe formulae for multiple roots thus obtained are based on the properties of the logarithmic Gauss map of the discriminant variety of a system of equations and on a linearization procedure for the system. The resulting formulae are of interest not only for theoretical aspects of the algebra of polynomials, but also for numerical mathematics and various areas of applied mathematics connected with finding critical points of polynomial maps. This article has certain goals and tasks for solving some engineering problems. The analysis of the situation regarding the applicability of risk management in the construction industry of the Russian Federation is presented.
