On rooted directed path graphs [PDF]

open access: yes, 2015
An asteroidal triple is a stable set of three vertices such that each pair is connected by a path avoiding the neighborhood of the third vertex. An asteroidal quadruple is a stable set of four vertices such that any three of them is an asteroidal triple.

Root product of lattices

open access: yesFilomat, 2012
In this paper a new product of lattices, the root product, is defined, and here are given some basic properties of this product. By multiplying two lattices a new lattice L is obtained. The lattice L posses better properties in terms of dimension and determinant.

VERTEX-ECCENTRICITY DESCRIPTORS IN DENDRIMERS

open access: yesStudia Universitatis Babes-Bolyai Chemia, 2017
In this paper, we present graph theoretical methods to compute several vertex-eccentricity-based molecular descriptors such as the eccentric connectivity index, total eccentricity, average eccentricity and first and second Zagreb eccentricity indices ...

Simulating quantum circuits using tree tensor networks [PDF]

open access: yesQuantum, 2023
We develop and analyze a method for simulating quantum circuits on classical computers by representing quantum states as rooted tree tensor networks. Our algorithm first determines a suitable, fixed tree structure adapted to the expected entanglement ...

Computing the Metric Dimension of a Graph from Primary Subgraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2017
Let G be a connected graph. Given an ordered set W = {w1, . . . , wk} ⊆ V (G) and a vertex u ∈ V (G), the representation of u with respect to W is the ordered k-tuple (d(u, w1), d(u, w2), . . .

Combinatorics of Rooted Trees and Hopf Algebras

open access: yes, 2002
We begin by considering the graded vector space with a basis consisting of rooted trees, graded by the count of non-root vertices. We define two linear operators on this vector space, the growth and pruning operators, which respectively raise and lower ...
