Link prediction with hyperbolic geometry [PDF]
Physical Review Research, 2020 Link prediction is a paradigmatic problem in network science with a variety of applications. In latent space network models this problem boils down to ranking pairs of nodes in the order of increasing latent distances between them. The network model with

Application of hyperbolic geometry in link prediction of multiplex networks [PDF]
Scientific Reports, 2019 Recently multilayer networks are introduced to model real systems. In these models the individuals make connection in multiple layers. Transportation networks, biological systems and social networks are some examples of multilayer networks.

Relating geometry descriptions to its derivatives on the web [PDF]
Proceedings of the 2019 European Conference on Computing in Construction, 2019 Sharing building information over the Web is becoming more popular, leading to advances in describing building models in a Semantic Web context. However, those descriptions lack unified approaches for linking geometry descriptions to building elements ...

Noncommutative Schwarzschild geometry and generalized uncertainty principle
European Physical Journal C: Particles and Fields, 2019 We discuss a possible link between the deformation parameter $$\Theta ^{\mu \nu }$$ Θμν arising in the framework of noncommutative geometry and the parameter $$\beta $$ β of the generalized uncertainty principle (GUP). We compute the shift of the Hawking

A link invariant from the symplectic geometry of nilpotent slices [PDF]
, 2004 We define an invariant of oriented links in S 3 using the symplectic geometry of certain spaces which arise naturally in Lie theory. More specifically, we present a knot as the closure of a braid, which in turn we view as a loop in configuration space ...

Geometry Interaction Knowledge Graph Embeddings [PDF]
AAAI Conference on Artificial Intelligence, 2022 Knowledge graph (KG) embeddings have shown great power in learning representations of entities and relations for link prediction tasks. Previous work usually embeds KGs into a single geometric space such as Euclidean space (zero curved), hyperbolic space

Geometry of Krylov complexity [PDF]
Physical Review Research, 2021 We develop a geometric approach to operator growth and Krylov complexity in many-body quantum systems governed by symmetries. We start by showing a direct link between a unitary evolution with the Liouvillian and the displacement operator of appropriate ...

Nonhomogeneous Stochastic Geometry Analysis of Massive LEO Communication Constellations [PDF]
IEEE Transactions on Communications, 2021 Providing truly ubiquitous connectivity requires development of low Earth orbit (LEO) satellite Internet, whose theoretical study is lagging behind network-specific simulations.
