Let $L \subset {\Bbb R}^3$ be the union of unit balls, whose centres lie on the $z$-axis, and are equidistant with distance $2d \in [2, 2\sqrt{2}]$. Then a packing of unit balls in ${\Bbb R}^3$ consisting of translates of $L$ has a density at most $\

We provide upper and lower bounds on the least-perimeter way to enclose and separate n regions of equal area in the plane. Along the way, inside the hexagonal honeycomb, we provide minimizers for each n .

Carbonbeton ist ein neuartiger Verbundwerkstoff, der seit ca. 20 Jahren in den Sonderforschungsbereichen (SFB) 528 und 532 erforscht wird. Abgesehen von vereinzelten Unikaten im Neubaubereich sind Einsatzgebiete bisher vornehmlich die Bereiche Sanier

We prove the following: If a finite family of unit (radius) disks has the property that the distance between every pair of centres is greater than 4/3 and every subset of at most five disks has a common transversal line, then all disks have a common

Let K denote an oval, a centrally symmetric compact convex domain with non-empty interior. A family of translates of K is said to have property T(k) if, for every subset of at most k translates, there exists a common line transversal intersecting all
