We investigate how it is possible to obtain different diffusive regimes from the Continuous Time Random Walk (CTRW) approach performing suitable changes for the waiting time and jumping distributions in order to get two or more regimes for the same diffusive process.
We also obtain diffusionlike equations related to these processes and investigate the connection of the results with anomalous diffusion. Keywords: random walk, anomalous diffusion, diffusive regimes. Caminhantes Aleatórios e diferentes regimes difusivos RESUMO.
Investigamos como é possível obter diferentes regimes difusivos do formalismo de caminhadas aleatórias com espaço-tempo contínuo fazendo mudanças adequadas na distribuição de tempos de espera e de saltos de forma a ...
