SIS epidemic propagation on hypergraphs [PDF]
Mathematical modeling of epidemic propagation on networks is extended to hypergraphs in order to account for both the community structure and the nonlinear dependence of the infection pressure on the number of infected neighbours.

Approximate counting of regular hypergraphs [PDF]
In this paper we asymptotically count d-regular k-uniform hypergraphs on n vertices, provided k is fixed and d=d(n)=o(n1/2). In doing so, we extend to hypergraphs a switching technique of McKay and Wormald.

Hypergraph regularity and random sampling
AbstractSuppose that a ‐uniform hypergraph satisfies a certain regularity instance (that is, there is a partition of given by the hypergraph regularity lemma into a bounded number of quasirandom subhypergraphs of prescribed densities). We prove that with high probability a large enough uniform random sample of the vertex set of also admits the same ...

Hypergraph limits: A regularity approach [PDF]
A sequence of $k$-uniform hypergraphs $H_1, H_2, \dots$ is convergent if the sequence of homomorphism densities $t(F, H_1), t(F, H_2), \dots$ converges for every $k$-uniform hypergraph $F$. For graphs, Lov sz and Szegedy showed that every convergent sequence has a limit in the form of a symmetric measurable function $W \colon [0,1]^2 \to [0,1]$.

On the spectrum of hypergraphs
Here we study the spectral properties of an underlying weighted graph of a non-uniform hypergraph by introducing different connectivity matrices, such as adjacency, Laplacian and normalized Laplacian matrices. We show that different structural properties

3D-Via Driven Partitioning for 3D VLSI Integrated Circuits
A 3D circuit is the stacking of regular 2D circuits. The advances on the fabrication and packaging technologies allowed interconnecting stacked 2D circuits by using 3D vias.

Embeddings and Ramsey numbers of sparse k-uniform hypergraphs
Chvatal, Roedl, Szemeredi and Trotter proved that the Ramsey numbers of graphs of bounded maximum degree are linear in their order. In previous work, we proved the same result for 3-uniform hypergraphs. Here we extend this result to k-uniform hypergraphs,

On a generalisation of Mantel's theorem to uniformly dense hypergraphs
For a $k$-uniform hypergraph $F$ let $\textrm{ex}(n,F)$ be the maximum number of edges of a $k$-uniform $n$-vertex hypergraph $H$ which contains no copy of $F$.

Constructing regular self-complementary uniform hypergraphs [PDF]
Summary: We examine the possible orders of t-subset-regular self-complementary \(k\)-uniform hypergraphs, which form examples of large sets of two isomorphic \(t\)-designs. We reformulate Khosrovshahi and Tayfeh -- Rezaie's necessary conditions on the order of these structures in terms of the binary representation of the rank \(k\), and these ...
