Abelian symmetries in the two-Higgs-doublet model with fermions
P. M. Ferreira, Joao P. Silva
We classify all possible implementations of an abelian symmetry in the two-Higgs-doublet model with fermions. We identify those symmetries which are consistent with non-vanishing q…
Nonminimal curvature-matter coupled wormholes with matter satisfying the null energy condition
Nadiezhda Montelongo Garcia, Francisco S. N. Lobo
Recently, exact solutions of wormhole geometries supported by a nonminimal curvature-matter coupling were found, where the nonminimal coupling minimizes the violation of the null e…
Phase diagrams of binary mixtures of patchy colloids with distinct numbers of patches: The network fluid regime
Daniel de las Heras, José M. Tavares, Margarida M. Telo da Gama
We calculate the network fluid regime and phase diagrams of binary mixtures of patchy colloids, using Wertheim's first order perturbation theory and a generalization of Flory-Stock…
Locally-finite connected-homogeneous digraphs
Robert Gray, Rognvaldur G. Moller
A digraph is connected-homogeneous if any isomorphism between finite connected induced subdigraphs extends to an automorphism of the digraph. We consider locally-finite connected-h…
The generalized Buckley-Leverett System. Solvability
Nikolai Chemetov, Wladimir Neves
We propose a new approach to the mathematical modeling of the Buckley- Leverett system, which describes two-phase flows in porous media. Considering the initial-boundary value prob…
Set-homogeneous directed graphs
Robert Gray, Dugald Macpherson, Cheryl E. Praeger +1
A directed graph is set-homogeneous if, whenever U and V are isomorphic finite subdigraphs, there is an automorphism g of the digraph with U^g=V. Here, extending work of Lachlan on…
