On Fixed-Order Book Thickness Parameterized by the Pathwidth of the Vertex Ordering
Theoretical Computer Science, 2020 Given a graph \(G=(V,E)\) and a fixed linear order \(\prec \) of V, the problem fixed-order book thickness asks whether there is a page assignment \(\sigma \) such that \(\langle \prec ,\sigma \rangle \) is a k-page book embedding of G. Recently, Bhore et al.(GD2019) presented an algorithm parameterized by the pathwidth of the vertex ordering (denoted ...

The book thickness of nilpotent graphs
Rocky Mountain Journal of Mathematics, 2022 Let \(R\) be a commutative ring with nonzero identity and let \(Z_N(R)=\{y \in R: yz ~\text{is}~ \text{nilpotent for some}~z\in R^*=R \setminus \{0\} \}.\) The nilpotent graph \(\Gamma_N (R)\) of \(R\) is the graph whose vertex set coincide with \(Z_N(R)^{*}=Z_N(R)\setminus \{0\}\) and there is an edge between two distinct vertices \(x\) and \(y\) if ...

1-Planar Graphs have Constant Book Thickness
, 2015 In a book embedding the vertices of a graph are placed on the “spine” of a book and the edges are assigned to “pages”, so that edges on the same page do not cross. In this paper, we prove that every 1-planar graph (that is, a graph that can be drawn on the plane such that no edge is crossed more than once) admits an embedding in a book with constant ...
