Transitive cornerations in maps
Primoz Potocnik, Alejandra Ramos-Rivera, Micael Toledo +1
A corner in a map is an edge-vertex-edge triple consisting of two distinct edges incident to the same vertex. A corneration is a set of corners that covers every arc of the map exa…
Symmetries of the Woolly Hat graphs
Leah Wrenn Berman, Hiroki Koike, Elias Mochan +3
A graph is edge-transitive if the natural action of its automorphism group on its edge set is transitive. An automorphism of a graph is semiregular if all of the orbits of the subg…
Bipartite Biregular Cages and Block Designs
Gabriela Araujo-Pardo, Alejandra Ramos-Rivera, Robert Jajcay
A bipartite biregular -graph is a bipartite graph of even girth having the degree set and satisfying the additional property that the vertices in the sam…
New structural results on tetravalent half-arc-transitive graphs
Alejandra Ramos Rivera, Primož Šparl
Tetravalent graphs admitting a half-arc-transitive subgroup of automorphisms, that is a subgroup acting transitively on its vertices and its edges but not on its arcs, are investig…
Arc Transitive Maps with underlying Rose Window Graphs
Isabel Hubard, Alejandra Ramos-Rivera, Primož Šparl
Let be a map with the underlying graph . The automorphism group induces a natural action on the set of all vertex-edge-face incident triples, called {…
