Oriented Interval Greedoids
Franco Saliola, Hugh Thomas
We propose a definition of an "oriented interval greedoid" that simultaneously generalizes the notion of an oriented matroid and the construction on antimatroids introduced by L. J…
On the canonical line bundle and negative holomorphic sectional curvature
Gordon Heier, Steven S. Y. Lu, Bun Wong
We prove that a smooth complex projective threefold with a Kähler metric of negative holomorphic sectional curvature has ample canonical line bundle. In dimensions greater than thr…
Graphical Probabilistic Routing Model for OBS Networks with Realistic Traffic Scenario
Martin Levesque, Halima Elbiaze
Burst contention is a well-known challenging problem in Optical Burst Switching (OBS) networks. Contention resolution approaches are always reactive and attempt to minimize the BLR…
On the prevalence and scientific impact of duplicate publications in different scientific fields (1980-2007)
Vincent Lariviere, Yves Gingras
The issue of duplicate publications has received a lot of attention in the medical literature, but much less in the information science community. This paper aims at analyzing the…
Solar-like oscillations in a massive star
K. Belkacem, R. Samadi, M. -J. Goupil +15
Seismology of stars provides insight into the physical mechanisms taking place in their interior, with modes of oscillation probing different layers. Low-amplitude acoustic oscilla…
Exotic left orderings of the free groups from the Dehornoy ordering
Adam Clay
We show that the restriction of the Dehornoy ordering to an appropriate free subgroup of the three-strand braid group defines a left ordering of the free group on k generators, k>1…
