Abstract
In this paper we study the geometric meaning of the roots of the Steiner polynomial in the 3-dimensional space. We give a complete characterization of the convex bodies in ℝ3 depending on the type of roots of their Steiner polynomials. Furthermore, we show that these roots are also related to the famous Blaschke problem and the Teissier conjecture.
Key words: Roots of the Steiner polynomial; Blaschke's problem; Teissier's conjecture; volume; surface area; integral mean curvature; circumradius; inradius
