    • Abstract


      We define a nonlinear model for fractional relaxation phenomena. We use 𝜖-expansion method to analyse this model. By studying the fundamental solutions of this model we find that when $t \to 0$ the model exhibits a fast decay rate and when $t \to \infty$ the model exhibits a power-law decay. By analysing the frequency response we find a logarithmic enhancement for the relative ratio of susceptibility.
