Improving upon a geometric inequality of third order - Toufik Mansour and Mark Shattuck We show that the best possible positive constant k in a certain geometric inequality of third order lies in the interval [0.14119,0.14364], which improves upon a previous known result where k=0. We also consider a comparable question concerning a fourth order version of the inequality. ✪ ✪ ✪ ✪ ✪ Link tải tài liệu: LINK TẢI TÀI LIỆU Theo LTTK Education
