Partial duality and closed 2-cell embeddings To Adrian Bondy on his 70th birthday
In 2009 Chmutov introduced the idea of partial duality for embeddings of graphs in surfaces. We discuss some alternative descriptions of partial duality, which demonstrate the symmetry between vertices and faces. One is in terms of band decompositions, and the other is in terms of the gem (graph-encoded map) representation of an embedding. We then use these to investigate when a partial dual is...
متن کاملClosed 2-cell embeddings of 4 cross-cap embeddable graphs
The strong embedding conjecture states that every 2-connected graph has a closed 2-cell embedding in some surface , i . e . an embedding that each face is bounded by a circuit in the graph . A graph is called k -crosscap embeddable if it can be embedded in the surface of non-orientable genus k . We confirm the strong embedding conjecture for 5-crosscap embeddable graphs . As a corollary , every...
متن کاملClosed 2-cell embeddings of graphs with no V8-minors
A closed 2-cell embedding of a graph embedded in some surface is an embedding such that each face is bounded by a cycle in the graph. The strong embedding conjecture says that every 2-connected graph has a closed 2-cell embedding in some surface. In this paper, we prove that any 2-connected graph without V8 (the M obius 4-ladder) as a minor has a closed 2-cell embedding in some surface. As a c...
متن کاملPoincaré Duality Embeddings and Fibrewise
We prove a relative Poincaré embedding theorem for maps of pairs into a Poincaré pair. This result has applications: it is the engine of the compression theorem of the author’s paper in Algebr. Geom. Topol. 2, (2002) 311–336, it yields a Poincaré space version of Hudson’s embedding theorem, and it can be used to equip 2-connected Poincaré spaces with handle decompositions.
متن کاملHigher Order Duality and Toric Embeddings
The notion of higher order dual varieties of a projective variety, introduced by Piene in 1983, is a natural generalization of the classical notion of projective duality. In this paper we study higher order dual varieties of projective toric embeddings. We express the degree of the second dual variety of a 2-jet spanned embedding of a smooth toric threefold in geometric and combinatorial terms,...
