Geometric Algebras of Light Cone Projective Graph Geometries [PDF]

open access: yesAdvances in Applied Clifford Algebras, 2023
A null vector is an algebraic quantity with the property that its square is zero. I denote the universal algebra generated by taking all sums and products of null vectors over the real or complex numbers by N\documentclass[12pt]{minimal} \usepackage ...

Community Detection in General Hypergraph Via Graph Embedding [PDF]

open access: yesJournal of the American Statistical Association, 2021
Conventional network data have largely focused on pairwise interactions between two entities, yet multi-way interactions among multiple entities have been frequently observed in real-life hypergraph networks.

Complete resolution of the circulant nut graph order-degree existence problem [PDF]

open access: yesArs Math. Contemp., 2022
A circulant nut graph is a non-trivial simple graph such that its adjacency matrix is a circulant matrix whose null space is spanned by a single vector without zero elements. Regarding these graphs, the order-degree existence problem can be thought of as

Columnar Storage and List-based Processing for Graph Database Management Systems [PDF]

open access: yesProceedings of the VLDB Endowment, 2021
We revisit column-oriented storage and query processing techniques in the context of contemporary graph database management systems (GDBMSs).

Alice  and the Caterpillar: A more descriptive null model for assessing data mining results [PDF]

open access: yesIndustrial Conference on Data Mining, 2022
We introduce novel null models for assessing the results obtained from observed binary transactional and sequence datasets, using statistical hypothesis testing.

Non-parallel graph of submodules of a module [PDF]

open access: yesمدل‌سازی پیشرفته ریاضی
A non-parallel submodules graph of M, denoted by G ∦ (M), is an undirected simple graph whose vertices are in one-to-one correspondence with all non-zero proper submodules of M and two distinct vertices are adjacent if and only if they are not parallel ...

Continuous Regular Functions [PDF]

open access: yesLogical Methods in Computer Science, 2020
Following Chaudhuri, Sankaranarayanan, and Vardi, we say that a function $f:[0,1] \to [0,1]$ is $r$-regular if there is a B\"{u}chi automaton that accepts precisely the set of base $r \in \mathbb{N}$ representations of elements of the graph of $f$.

Discrete Random Walks on One-Sided ``Periodic'' Graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
In this paper we consider discrete random walks on infinite graphs that are generated by copying and shifting one finite (strongly connected) graph into one direction and connecting successive copies always in the same way.

A Spinorial Formulation of the Maximum Clique Problem of a Graph [PDF]

open access: yes, 2006
We present a new formulation of the maximum clique problem of a graph in complex space. We start observing that the adjacency matrix A of a graph can always be written in the form A = B B where B is a complex, symmetric matrix formed by vectors of zero ...
