DOI: 10.1088/1742-5468/aa64fa
Abstract: This paper investigates the temporal anomalous diffusion and drift of particles in a comb backbone. Fractional Cattaneo–Christov flux is introduced and the formulated governing equation has a Dirac delta function and mixed partial derivative which… read more here.

Abstract: A nearly-integrable dynamical system has a natural formulation in terms of actions, y (nearly constant), and angles, x (nearly rigidly rotating with frequency Ω(y)).We study angleaction maps that are close to symplectic and have a… read more here.
