Sampling theory of jointly bandlimited time-vertex graph signals
Signal Processing, 2023 Time-vertex graph signal (TVGS) models describe time-varying data with irregular structures. The bandlimitedness in the joint time-vertex Fourier spectral domain reflects smoothness in both temporal and graph topology. In this paper, we study the critical sampling of three types of TVGS including continuous-time signals, infinite-length sequences, and ...

Relation algebras and vertex conditions in graph theory
, 2018 The scheme associated with a graph is an association scheme iff the graph is strongly regular. Consider the problem of extending such an association scheme to a superscheme. The obstacles can be expressed in terms of f-vertex conditions. If a graph does not satisfy the i-vertex condition, a presuperscheme associated with it cannot be erected beyond the

A rough set method for the vertex cover problem in graph theory
Journal of Intelligent & Fuzzy Systems, 2016 In this paper, we first establish a Multi-Relation Granular Computing model by a given graph, and point out that all the reducts of the constructed Multi-Relation Granular Computing model are exactly all the minimal vertex covers of the corresponding graph.

Configurations of DNA cages based on plane graphs and vertex junctions
Journal of Physics A: Mathematical and Theoretical, 1965Surface wave phase velocities for an inhomogeneous medium are usually given as eigenvalues of the wave equation. This is a differential equation (Love waves) or pair of differential equations (Rayleigh waves) of the second order. By means of a change of variable the problem is reducible to finding the zeros of a first‐order differential equation or ...

[Most frequent themes in Editorials of Vertex journal (1990-2019) analyzed by graph theory].
Vertex (Buenos Aires, Argentina), 2022The analysis of Editorials is a little explored topic, which can facilitate the understanding of historical processes and changes in Psychiatry. In the case of de Vertex Revista Argentina de Psiquiatría, the Editorials were written by the same person for 30 years. The most frequently used thematic areas were studied, using graph theory, to characterize
