Spin networks and the big bang singularity avoidance in the AdS/CFT correspondence
Carlos Silva
We propose a new version of the correspondence, where polymer structures similar to Loop Quantum Cosmology spin networks can be induced on an isotropic and homogeneous fl…
Channel Estimation for Intelligent Reflecting Surface Assisted MIMO Systems: A Tensor Modeling Approach
Gilderlan T. de Araújo, André L. F. de Almeida, Rémy Boyer
Intelligent reflecting surface (IRS) is an emerging technology for future wireless communications including 5G and especially 6G. It consists of a large 2D array of (semi-)passive…
Small-time global exact controllability to the trajectories for the viscous Boussinesq system
F. W. Chaves-Silva, E. Fernández-Cara, K. Le Balc'h +2
In this paper, we deal with the global exact controllability to the trajectories of the Boussinesq system. We consider 2D and 3D smooth bounded domains. The velocity field of the f…
Polar gravitational perturbations and quasinormal modes of a loop quantum gravity black hole
M. B. Cruz, F. A. Brito, C. A. S. Silva
In this work, we have calculated the polar gravitational quasinormal modes for a quantum corrected black hole model, that arises in the context of Loop Quantum Gravity, known as Se…
Class of solutions of the Wheeler-DeWitt equation with ordering parameter
H. S. Vieira, V. B. Bezerra, C. R. Muniz +2
In this letter, we discuss the Wheeler-DeWitt equation with an ordering parameter in the Friedmann-Robertson-Walker universe. The solutions when the universe was very small and at…
Residuated implications derived from quasi-overlap functions on lattices
Rui Paiva, Benjamín Bedregal, Regivan Santiago
In this paper, we introduce the concept of residuated implications derived from quasi-overlap functions on lattices and prove some related properties. In addition, we formalized th…
