Degrees in oriented hypergraphs and Ramsey p-chromatic number
Yair Caro, Adriana Hansberg
The family of graphs having an orientation such that for every vertex either (outdegree) or (indegree) have been investigated re…
Generic singular configurations of linkages
David Blanc, Nir Shvalb
We study the topological and differentiable singularities of the configuration space C(Γ) of a mechanical linkage Γin d-dimensional Euclidean space, defining an inductive sufficien…
Approximating the Diameter of Planar Graphs in Near Linear Time
Oren Weimann, Raphael Yuster
We present a -approximation algorithm running in time for finding the diameter of an undirected planar graph with non-negative edge lengths.
Locally class-presentable and class-accessible categories
Boris Chorny, Jiri Rosicky
We generalize the concepts of locally presentable and accessible categories. Our framework includes such categories as small presheaves over large categories and ind-categories. Th…
Higher pentagram maps, weighted directed networks, and cluster dynamics
Michael Gekhtman, Michael Shapiro, Serge Tabachnikov +1
The pentagram map that associates to a projective polygon a new one formed by intersections of short diagonals was introduced by R. Schwartz and was shown to be integrable by V. Ov…
Interval Graphs with Containment Restrictions
Jeffrey Beyerl, Robert E. Jamison
An interval graph is proper iff it has a representation in which no interval contains another. Fred Roberts characterized the proper interval graphs as those containing no induced…
