Fixed Point Homing Shuffles Autor Parlett, Jonathan

“…We study a family of maps from $S_n \to S_n$ we call fixed point homing shuffles. These maps generalize a few known problems such as Conway's Topswops, and a…”

Proper edge colorings of planar graphs with rainbow ${C}_{4}$‐s Autor Gyárfás, András, Martin, Ryan, Ruszinko, Miklos, Sárközy, Gábor N.

“…We call a proper edge coloring of a graph G $G$ a B-coloring if every 4-cycle of G $G$ is colored with four different colors. Let ${q}_{B}(G)$ denote the…”

On the enumeration of plane bipolar posets and transversal structures Autor Fusy, Éric, Narmanli, Erkan, Schaeffer, Gilles

“…We show that plane bipolar posets (i.e., plane bipolar orientations with no transitive edge) and transversal structures can be set in correspondence to certain…”

Smallest $C_{2l+1}$-critical graphs of odd-girth $2k+1 Autor Beaudou, Laurent, Foucaud, Florent, Naserasr, Reza

“…Given a graph H, a graph G is called H-critical if G does not admit a homomorphism to H, but any proper subgraph of G does. Observe that K k−1-critical graphs…”
