Based on the extrapolation theory and a sixth order compact difference scheme, new extrapolation interpolation operator and extrapolation cascadic multigrid methods for two dimensional Poisson equation are presented. The new extrapolation interpolation operator is used to provide a better initial value on refined grid. The convergence of the new methods are(More)
Mating systems have important implications for understanding the population and evolutionary dynamics of species. However, most theoretical and empirical work on vertebrate mating systems has focused on bird and mammalian species, and the mating systems of amphibian remain poorly understood. To better understand the mating systems of amphibian, in this(More)
