Boxicity and Threshold Dimension of Zero Divisor Graphs
Marco Caoduro, Meike Neuwohner
The zero divisor graph of a finite commutative ring has as vertices the non-zero zero divisors of , with an edge between two elements exactly when their product is ze…
Cosigning Crossing Families and Outer-Planar Gadgets
Ahmad Abdi, Mahsa Dalirrooyfard, Meike Neuwohner
Let be a crossing family over ground set , that is, for any two sets with nonempty intersection and proper union, both sets are in . Let $…
Strong orientation of a connected graph for a crossing family
Ahmad Abdi, Mahsa Dalirrooyfard, Meike Neuwohner
Given a connected graph and a crossing family over ground set such that for every , we prove there exists a strong or…
Characterizing unimodular laminar hypergraphs via forbidden subhypergraphs
Marco Caoduro, Meike Neuwohner, Joseph Paat
The incidence matrix of a graph is totally unimodular if and only if the graph is bipartite, i.e., it contains no odd cycles. We extend the characterization of total unimodularity…
