Abstract

This article is a short supplement to our previously published paper, in which we prove that each semialgebraic set can be represented as a projection of a solution set of some system of linear equations with dependent coefficients. The new results says that interval occurring can be chosen as narrow as wanted. This new result is proven by a simple linear transformation.
