Large flames in rooted acyclic digraphs without backward-infinite paths
Attila Joó, Qiuzhenyu Tao
An -rooted digraph is a flame if for each non-root vertex , there is a set of edge-disjoint directed paths from to that covers all ingoing edges of . The study of…
Time-resolved protoplanetary disk physics in DQ Tau with JWST
Á. Kóspál, P. Ábrahám, V. V. Akimkin +17
Accretion variability is ubiquitous in YSOs. While large outbursts may strongly affect the disk, the effects of moderate bursts are less understood. We aim to study the physical re…
A structure theorem for rooted connectivity in bidirected graphs
Tara Abrishami, Nathan Bowler, Attila Joó +2
Recently, bidirected graphs have received increasing attention from the graph theory community with both structural and algorithmic results. Bidirected graphs are a generalization…
Wild generalised truncation of infinite matroids
J. Pascal Gollin, Attila Joó
For , the -truncation of a matroid of rank at least is the matroid whose bases are the -element independent sets of . One can extend this defin…
Hindrance from a wasteful common independent set
Attila Joó
For (potentially infinite) matroids and , an -hindrance is a set that is independent but not spanning in . This concept was introdu…
