Fundraising and vote distribution: a non-equilibrium statistical approach

H. P. M. Melo, N. A. M. Araujo, J. S. Andrade

The number of votes correlates strongly with the money spent in a campaign, but the relation between the two is not straightforward. Among other factors, the output of a ballot dep…

Antisymmetric tensor propagator with spontaneous Lorentz violation

R. V. Maluf, A. A. Araujo Filho, W. T. Cruz +1

In this work, we study the spontaneous Lorentz symmetry breaking due to an antisymmetric 2-tensor field in Minkowski spacetime. For a smooth quadratic potential, the spectrum of th…

Configurational entropy and Newton's Law in double sine-Gordon braneworlds

W. T. Cruz, D. M. Dantas, R. V. Maluf +1

In this work, we evaluate the Shannon-like entropic measure of spatially-localized functions for a five-dimensional braneworld generated by a double sine-Gordon (DSG) potential. Th…

On Finding a First-Order Sentence Consistent with a Sample of Strings

Thiago Alves Rocha, Ana Teresa Martins, Francicleber Martins Ferreira

We investigate the following problem: given a sample of classified strings, find a first-order sentence of minimal quantifier rank that is consistent with the sample. We represent…

Connected greedy coloring $H$ -free graphs

Esdras Mota, Ana Silva, Leonardo Sampaio

A connected ordering $(v_{1}, v_{2}, \dots, v_{n})$ of $V (G)$ is an ordering of the vertices such that $v_{i}$ has at least one neighbour in ${v_{1}, \dots, v_{i - 1}}$ for every $i \in…

Overdamped dynamics of particles with repulsive power-law interactions

André A. Moreira, César M. Vieira, Humberto A. Carmona +2

We investigate the dynamics of overdamped $D$ -dimensional systems of particles repulsively interacting through short-ranged power-law potentials, $V (r) \sim r^{- λ} (λ / D > 1)$ . We sho…

Conformal gradient vector fields on Riemannian manifolds with boundary

Israel Evangelista, Emanuel Viana

Let $(M^{n}, g)$ be an $n$ -dimensional compact connected Riemannian manifold with smooth boundary. We show that the presence of a nontrivial conformal gradient vector field on $M$ , wi…
