Graph curvature and Laplacian operators form a vibrant area of research at the intersection of differential geometry and graph theory. The concept of graph curvature, inspired by classical Ricci ...

MicroCloud Hologram Inc. (NASDAQ: HOLO), ("HOLO" or the "Company"), a technology service provider, released learnable quantum spectral filter technology for hybrid graph neural networks. This ...

In this study, we aim to determine the unique tetracyclic graph that maximizes the signless Laplacian Estrada index (SLEE) among all tetracyclic graphs. The SLEE of a graph Ω is defined as the sum of ...

MicroCloud Hologram ’s approach uses a logarithmic encoding method to reduce the number of qubits needed, representing an N-dimensional feature space using just log (N) qubits. The system forms an end ...

This is a preview. Log in through your library . Abstract A signed graph consists of a (simple) graph G = (V, E) together with a function σ : E {+; −} called signature. Matrices can be associated to ...
