Semi-algebraic properties of Minkowski sums of a twisted cubic segment

Arthur Bik, Adam Czapliński, Markus Wageringel

We find a semi-algebraic description of the Minkowski sum ${\mathcal{A}}_{3,n}$ of $n$ copies of the bounded twisted cubic $\{(t,t^2,t^3)\mid -1\le t\le 1\}$ for each integer $n\ge…
