Pairwise Reflection Symmetry in Generalized Latin Rectangles
Enrico Iurlano, Günther R. Raidl
Many combinatorial designs ask for equal distribution of given symbols across the entries of a matrix. The paramount examples are Latin squares, where each symbol from $\{1,\dots,n…

Putting Tutte's counterexample to Tait's conjecture in perspective to hamiltonicity and non-hamiltonicity in certain planar cubic graphs
Herbert Fleischner, Enrico Iurlano, Günther R. Raidl
Using the graphs of prisms and Tutte Fragments, we construct an infinite family of hamiltonian and non-hamiltonian graphs in which Tutte's counterexample to Tait's conjecture appea…

Signed double Roman domination on cubic graphs
Enrico Iurlano, Tatjana Zec, Marko Djukanovic +1
The signed double Roman domination problem is a combinatorial optimization problem on a graph asking to assign a label from to each vertex feasibly, such that the…
