Barycentric Drawings of Periodic Graphsh, are unique up to affine transformations, and provide a versatile tool not only in drawing, but also in computation. Example applications include symmetric convex drawing in dimension 2 as well as determining topological types of crystals and computing their ideal symmetry groups.CULP 发表于 2025-3-27 01:44:01
Three-Dimensional Grid Drawings with Sub-quadratic Volumegments representing the edges are pairwise non-crossing. A . volume bound is proved for three-dimensional grid drawings of graphs with bounded degree, graphs with bounded genus, and graphs with no bounded complete graph as a minor. The previous best bound for these graph families was .. These result打折 发表于 2025-3-27 05:30:49

We consider the question how complicated need to be the polygons in a polygon-circle representation of a graph..Let cmp (.) denote the minimum . such that every polygon-circle graph on . vertices is the intersection graph of .顽固 发表于 2025-3-28 14:01:46
Microbial Adhesion and Aggregationts connecting the appropriate points. A noncrossing Hamiltonian path in a geometric graph is a Hamiltonian path which does not contain any intersecting pair of edges. In the paper, we study a problem asked by Micha Perles: Determine a function ., where .(.) is the largest number . such that when we
