We set out to obtain estimates of the Laplacian Spectrum of Riemannian manifolds with non-empty boundary. This was achieved using standard doubled manifold techniques. In simple terms, we pasted two copies of the same manifold along their common boundary

On singularity and properties of eigenvectors of complex Laplacian matrix of multidigraphs
In this article, we associate a Hermitian matrix to a multidigraph G. We call it the complex Laplacian matrix of G and denote it by [Formula: see text]. It is shown that the complex Laplacian matrix is a generalization of the Laplacian matrix of a graph.

The Largest Laplacian and Signless Laplacian H-Eigenvalues of a Uniform Hypergraph [PDF]
In this paper, we show that the largest Laplacian H-eigenvalue of a $k$-uniform nontrivial hypergraph is strictly larger than the maximum degree when $k$ is even. A tight lower bound for this eigenvalue is given.

Integral Laplacian graphs with a unique repeated Laplacian eigenvalue, I
AbstractThe setSi,n={0,1,2,…,n−1,n}\{i}{S}_{i,n}=\left\{0,1,2,\ldots ,n-1,n\right\}\setminus \left\{i\right\},1⩽i⩽n1\leqslant i\leqslant n, is called Laplacian realizable if there exists an undirected simple graph whose Laplacian spectrum isSi,n{S}_{i,n}. The existence of such graphs was established by Fallat et al.

This study harnesses hydrodynamic flows to generate, confine and stimulate stem cell spheroids, enabling the large‐scale production of extracellular vesicles (EVs). This innovative method not only streamlines spheroid formation and subsequent EV release in a single, integrated process, but also ensures the generation of EVs with enhanced biological ...

Abstract We propose a hierarchical energy management scheme for aggregating Distributed Energy Resources (DERs) for grid flexibility services. To prevent a direct participation of numerous prosumers in the wholesale electricity market, aggregators, as self‐interest agents in our scheme, incentivize prosumers to provide flexibility. We firstly model the

Synthesis, Structure, and Reactivity of a Magnesium(0) Complex with a Polarized Mgδ−─Caδ+ Bond
Mixing metals: The elusive unsupported two‐center‐two‐electron Mg─Ca bond has been realized by using a combination of β‐diketiminate and amidinate ligands. Due to electronegativity differences (Mg: 1.31, Ca: 1.00) the formal oxidation states are Mg0─CaII.

Cospectral constructions for several graph matrices using cousin vertices
Graphs can be associated with a matrix according to some rule and we can find the spectrum of a graph with respect to that matrix. Two graphs are cospectral if they have the same spectrum.
