Hypersymmetric extensions of Maxwell Chern-Simons gravity in (2+1) dimensions

Ricardo Caroca, Patrick Concha, Javier Matulich +2

We present a consistent way of coupling three-dimensional Maxwell Chern-Simons gravity theory with massless spin- $\frac{5}{2}$ gauge fields. We first introduce the simplest hyper-M…

The (super)conformal BMS $_{3}$ algebra

Oscar Fuentealba, Hernan A. Gonzalez, Alfredo Perez +2

The conformal extension of the BMS $_{3}$ algebra is constructed. Apart from an infinite number of 'superdilatations,' in order to incorporate 'superspecial conformal transformation…

Pivot Selection for Median String Problem

Pedro Mirabal, José Abreu, Oscar Pedreira

The Median String Problem is W[1]-Hard under the Levenshtein distance, thus, approximation heuristics are used. Perturbation-based heuristics have been proved to be very competitiv…

Greybody Factors of Massive Charged Fermionic Fields in a Charged Two-Dimensional Dilatonic Black Hole

Ramon Becar, P. A. Gonzalez, Joel Saavedra +1

We study massive charged fermionic perturbations in the background of a charged two-dimensional dilatonic black hole, and we solve the Dirac equation analytically. Then, we compute…

Dirac quasinormal modes of two-dimensional charged Dilatonic Black Holes

Ramon Becar, P. A. Gonzalez, Y. Vasquez

We study charged fermionic perturbations in the background of two-dimensional charged Dilatonic black holes, and we present the exact Dirac quasinormal modes. Also, we study the st…

Fermionic greybody factors of two and five-dimensional dilatonic black holes

Ramón Becar, P. A. González, Yerko Vásquez

We study fermionic perturbations in the background of a two and five-dimensional dilatonic black holes. Then, we compute the reflection and transmission coefficients and the absorp…
