Light propagation and gravitational lensing effects in charged Kalb-Ramond spacetime in nonlinear electrodynamics
C. F. S. Pereira, Marcos V. de S. Silva, A. R. Soares +3
In this work, we theoretically investigate the deflection of light for strong- and weak-field regimes in the background of an electrically charged BH described in Kalb-Ramond gravi…
Circadian Clock Model with Sequestration Repression Motif: Existence of Periodic Orbits and Entrainment Properties
Benjamin Böbel, Madalena Chaves, Jean-Luc Gouzé
Protein sequestration motifs appear in many biological regulatory networks and introduce special properties into the network dynamics. Sequestration can be described as a mode of i…
Spectral Theory Approach for a Class of Radial Indefinite Variational Problems
Mayra Soares, Liliane Maia
Considering the radial nonlinear Schrodinger equation - Δu + V(x)u = g(x,u) in R^N, N \geq 3 we aim to find a radial nontrivial solution for it, where V changes sign ensuring this…
Simplicity of augmentation submodules for transformation monoids
M. H. Shahzamanian, B. Steinberg
For finite permutation groups, simplicity of the augmentation submodule is equivalent to -transitivity over the field of complex numbers. We note that this is not the case for t…
Stability of a heteroclinic network and its cycles: a case study from Boussinesq convection
Olga Podvigina, Sofia B. S. D. Castro, Isabel S. Labouriau
This article is concerned with three heteroclinic cycles forming a heteroclinic network in . The stability of the cycles and of the network are studied. The cycles a…
A strong invariance principle for the elephant random walk
Cristian F. Coletti, Renato Gava, Gunter M. Schütz
We consider a non-Markovian discrete-time random walk on with unbounded memory called the elephant random walk (ERW). We prove a strong invariance principle for the ER…
