R-hulloid of the vertices of a tetrahedron
Marco Longinetti, Simone Naldi, Adriana Venturi
The -hulloid, in the Euclidean space , of the set of vertices of a tetrahedron is the minimal closed set containing such that its complement is the uni…
On the complements of union of open balls and related set classes
Marco Longinetti, Paolo Manselli, Adriana Venturi
Let a -body be a closed set, complement of union of open balls of radius in the Euclidean space. Properties generalizing similar ones for convex sets are proved for the fami…
On the configurations of four spheres supporting the vertices of a tetrahedron
Marco Longinetti, Simone Naldi
A reformulation of the three circles theorem of Johnson with distance coordinates to the vertices of a triangle is explicitly represented in a polynomial system and solved by symbo…
Convex Hulls of Orbits and Orientations of a Moving Protein Domain
Marco Longinetti, Luca Sgheri, Frank Sottile
We study the facial structure and Carathéodory number of the convex hull of an orbit of the group of rotations in R^3 acting on the space of pairs of anisotropic symmetric 3\times…
