[BOG][B] Higher-order systems

F Battiston, G Petri - 2022 - Springer
Over the last 20 years networks have emerged as the paradigmatic framework to model
complex systems. Yet, as simple collections of nodes and links, they are intrinsically limited …

Nonbacktracking spectral clustering of nonuniform hypergraphs

P Chodrow, N Eikmeier, J Haddock - SIAM Journal on Mathematics of Data …, 2023 - SIAM
Spectral methods offer a tractable, global framework for clustering in graphs via eigenvector
computations on graph matrices. Hypergraph data, in which entities interact on edges of …

Graphs, simplicial complexes and hypergraphs: spectral theory and topology

R Mulas, D Horak, J Jost - Higher-order systems, 2022 - Springer
In this chapter we discuss the spectral theory of discrete structures such as graphs, simplicial
complexes and hypergraphs. We focus, in particular, on the corresponding Laplace …

Structural reduction of chemical reaction networks based on topology

Y Hirono, T Okada, H Miyazaki, Y Hidaka - Physical Review Research, 2021 - APS
We develop a model-independent reduction method of chemical reaction systems based on
the stoichiometry, which determines their network topology. A subnetwork can be eliminated …

Random walks and Laplacians on hypergraphs: When do they match?

R Mulas, C Kuehn, T Böhle, J Jost - Discrete Applied Mathematics, 2022 - Elsevier
We develop a general theory of random walks on hypergraphs which includes, as special
cases, the different models that are found in literature. In particular, we introduce and …

Spectral theory of weighted hypergraphs via tensors

F Galuppi, R Mulas, L Venturello - Linear and Multilinear Algebra, 2023 - Taylor & Francis
One way to study a hypergraph is to attach to it a tensor. Tensors are a generalization of
matrices, and they are an efficient way to encode information in a compact form. In this …

Hyper-diffusion on multiplex networks

R Ghorbanchian, V Latora… - Journal of Physics …, 2022 - iopscience.iop.org
Multiplex networks describe systems whose interactions can be of different nature, and are
fundamental to understand complexity of networks beyond the framework of simple graphs …

Incorporating non-local anyonic statistics into a graph decomposition

M Mühlhauser, V Kott, KP Schmidt - SciPost Physics Core, 2024 - scipost.org
In this work we describe how to systematically implement a full graph decomposition to set
up a linked-cluster expansion for the topological phase of Kitaev's toric code in a field. This …

[HTML][HTML] An improved adaptive median filtering algorithm for radar image co-channel interference suppression

N Li, T Liu, H Li - Sensors, 2022 - mdpi.com
In order to increase the accuracy of ocean monitoring, this paper proposes an improved
adaptive median filtering algorithm based on the tangential interference ratio to better …

Calculus of variations on hypergraphs

M Shao, Y Tian, L Zhao - The Journal of Geometric Analysis, 2025 - Springer
We have established a coherent framework for applying variational methods to partial
differential equations on hypergraphs, which includes the propositions of calculus and …
