Flow polytopes for extensions of bipartite graphs
Benjamin Braun, Kaitlin Bruegge, Robert Davis +1
The space of unit flows on a finite acyclic directed graph is a lattice polytope called the flow polytope of the graph. Given a bipartite graph with minimum degree at least two…
Alexander duals of symmetric simplicial complexes and Stanley-Reisner Ideals
Ayah Almousa, Kaitlin Bruegge, Martina Juhnke-Kubitzke +2
Given an ascending chain of $\Sym$-invariant squarefree monomial ideals, we study the corresponding chain of Alexander duals .…
Facets of Random Symmetric Edge Polytopes, Degree Sequences, and Clustering
Benjamin Braun, Kaitlin Bruegge, Matthew Kahle
Symmetric edge polytopes are lattice polytopes associated with finite simple graphs that are of interest in both theory and applications. We investigate the facet structure of symm…
Triangulations of Flow Polytopes, Ample Framings, and Gentle Algebras
Matias von Bell, Benjamin Braun, Kaitlin Bruegge +4
The cone of nonnegative flows for a directed acyclic graph (DAG) is known to admit regular unimodular triangulations induced by framings of the DAG. These triangulations restrict t…
Facets of Symmetric Edge Polytopes for Graphs with Few Edges
Benjamin Braun, Kaitlin Bruegge
Symmetric edge polytopes, also called adjacency polytopes, are lattice polytopes determined by simple undirected graphs. We introduce the integer array \(\mathrm{maxf}(n,m)\) givin…
The relentless variability of Mrk 421 from the TeV to the radio
Axel Arbet-Engels, Dominik Baack, Matteo Balbo +22
The origin of the gamma-ray emission of the blazar Mrk 421 is still a matter of debate. We used 5.5 years of unbiased observing campaign data, obtained using the FACT telescope and…
The extreme HBL behaviour of Markarian 501 during 2012
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +276
A multiwavelength campaign was organized to take place between March and July of 2012. Excellent temporal coverage was obtained with more than 25 instruments, including the MAGIC,…
Mirror Position Determination for the Alignment of Cherenkov Telescopes
J. Adam, M. L. Ahnen, D. Baack +27
Imaging Atmospheric Cherenkov Telescopes (IACTs) need imaging optics with large apertures to map the faint Cherenkov light emitted in extensive air showers onto their image sensors…
Bokeh Mirror Alignment for Cherenkov Telescopes
M. L. Ahnen, D. Baack, M. Balbo +29
Imaging Atmospheric Cherenkov Telescopes (IACTs) need imaging optics with large apertures and high image intensities to map the faint Cherenkov light emitted from cosmic ray air sh…
Normalized and Asynchronous Mirror Alignment for Cherenkov Telescopes
M. L. Ahnen, D. Baack, M. Balbo +29
Imaging Atmospheric Cherenkov Telescopes (IACTs) need imaging optics with large apertures and high image intensities to map the faint Cherenkov light emitted from cosmic ray air sh…
