The K-essence flow seen from the preferred frame $S_{V}$ . A scalar field theory with Landau superfluid structure

Rodrigo Francisco dos Santos, Luis Gustavo de Almeida, A. C. Amaro de Faria

We study the hypothesis of deformation of the invariance of Lorentz transformations produced by the introduction of a universal minimum velocity relative to a preferred frame. Our…

Rigidity results for Riemann solitons

Tokura Willian, Barboza Marcelo, Batista Elismar +1

In this paper we take a look at conditions that make a Riemann soliton trivial, compacity being one of them. We also show that the behaviour at infinity of the gradient field of a…

Constraints and correlations of nuclear matter parameters from a density-dependent van der Waals model

M. Dutra, B. M. Santos, O. Lourenço

A recently proposed density-dependent van der Waals model, with only $4$ free parameters adjusted to fix binding energy, saturation density, symmetry energy, and incompressibility,…

The Fubini Theorem for Normal Lie Subgroups of Index $2 n$

Leandro Nery de Oliveira, Marcos Aurélio de Alcântara

Let $Γ_{+}$ be a normal subgroup of index $2 n$ of a group $Γ$ and $γ_{i} \in Γ ∖ Γ_{+}$ be involutions. We first prove that if $Γ= Γ_+ \rtimes (\mathbb{Z}_2(γ_1) \times \cdots \ti…

Density-dependent van der Waals model under the GW170817 constraint

O. Lourenço, M. Dutra, C. H. Lenzi +3

We propose a density-dependent function for the attractive interaction in the original van der Waals model to correctly describe the flow constraint at the high-density regime of t…

Equivariant mappings and invariant sets on Minkowski space

Miram Manoel, Leandro Nery de Oliveira

In this paper we introduce the systematic study of invariant functions and equivariant mappings defined on Minkowski space under the action of the Lorentz group. We adapt some know…
