Title: The Euclidean Steinitz–Bergström theorem.

Abstract: Every prescribed-order finite sequence of vectors in the Euclidean unit ball of ℝd has one signing for which every signed prefix has norm at most $C{}sqrt d$, with C absolute and independent of the sequence length. Consequently, every indexed zero-sum family of unit-ball vectors admits an ordering with the same bound for its unsigned partial sums. This determines the Euclidean Steinitz constant up to absolute factors, $S_2(d)={}Theta({}sqrt d)$, and resolves the Euclidean Steinitz–Bergström conjecture.
