    Psi-Series Solution of Fractional Ginzburg-Landau Equation

    Full text link
    One-dimensional Ginzburg-Landau equations with derivatives of noninteger order are considered. Using psi-series with fractional powers, the solution of the fractional Ginzburg-Landau (FGL) equation is derived. The leading-order behaviours of solutions about an arbitrary singularity, as well as their resonance structures, have been obtained. It was proved that fractional equations of order alphaalpha with polynomial nonlinearity of order ss have the noninteger power-like behavior of order α/(1−s)\alpha/(1-s) near the singularity.Comment: LaTeX, 19 pages, 2 figure

    Diffusion on middle-ξ\xi Cantor sets

    Full text link
    In this paper, we study CζC^{\zeta}-calculus on generalized Cantor sets, which have self-similar properties and fractional dimensions that exceed their topological dimensions. Functions with fractal support are not differentiable or integrable in terms of standard calculus, so we must involve local fractional derivatives. We have generalized the CζC^{\zeta}-calculus on the generalized Cantor sets known as middle-ξ\xi Cantor sets. We have suggested a calculus on the middle-ξ\xi Cantor sets for different values of ξ\xi with 0<ξ<10<\xi<1. Differential equations on the middle-ξ\xi Cantor sets have been solved, and we have presented the results using illustrative examples. The conditions for super-, normal, and sub-diffusion on fractal sets are given.Comment: 15 pages, 11 figure
