Na Relatividade Geral, em sistemas com uma massa dominante, a curvatura do espaço-tempo é descrita pela métrica de Schwarzschild. Contudo, obter seus coeficientes métricos do campo gravitacional desta massa exige, em geral, o uso de ferramentas m

In magnetically confined plasma, it is possible to qualitatively describe the magnetic field configuration via phase spaces of suitable symplectic maps. These phase spaces are of mixed type, where chaos coexists with regular motion, and the complete

Como aplicação didática da Relatividade Geral, implementamos, a partir da métrica de Schwarzschild, uma simulação da órbita da estrela S2 em torno do buraco negro massivo Sagitário A*. Verificamos que a orbita simulada é quase uma elipse, co

We investigate the transient dynamics of the Fisher equation under nonlinear diffusion and fractional operators. Firstly, we investigate the effects of the nonlinear diffusivity parameter in the integer-order Fisher equation, by considering a Gaussia

Spiral waves are spatial-temporal patterns that can emerge in different systems as heart tissues, chemical oscillators, ecological networks and the brain. These waves have been identified in the neocortex of turtles, rats, and humans, particularly du

The fractional reaction–diffusion equation has been used in many real-world applications in fields such as physics, biology, and chemistry. Motivated by the huge application of fractional reaction–diffusion, we propose a numerical scheme to solve
