One-parameter Darboux-deformed Fibonacci numbers
H. C. Rosu, S. C. Mancas
One-parameter Darboux deformations are effected for the simple ODE satisfied by the continuous generalizations of the Fibonacci sequence recently discussed by Faraoni and Atieh [Sy…
Factorization conditions for nonlinear second-order differential equations
G. Gonzalez, H. C. Rosu, O. Perez-Cornejo +1
For the case of nonlinear second-order differential equations with a constant coefficient of the first derivative term and polynomial nonlinearities, the factorization conditions o…
Relativistic hyperbolic motion and its higher order kinematic quantities
Ivan Perez-Roman, Haret C. Rosu
We investigate the kinematics of the motion of an observer with constant proper acceleration (relativistic hyperbolic motion) in 1+1 and 1+3 dimensional Minkowski spacetimes. We pr…
Vanishing Poynting observers and electromagnetic field classification in Kerr and Kerr-Newman spacetimes
H. Vargas-Rodríguez, H. C. Rosu, M. G. Medina-Guevara +2
We consider electromagnetic fields having an angular momentum density in a locally non-rotating reference frame in Schwarzschild, Kerr, and Kerr-Newman spacetimes. The nature of su…
