Spreading Speeds of Monostable Equations in Locally Spatially Variational Habitat with Hybrid Dispersal
Liang Kong
Keywords:Monostable equations, random dispersal, nonlocal dispersal, localized spatial inhomogeneity, principal eigenvalue, sub-solution, super-solution, comparison principle, spreading speeds.
      In this paper, we consider a monostable model with hybrid dispersal. This model characterizes the time evolution of a population which disperses both locally and non-locally in locally spatially inhomogeneous media. It is shown that such equation has a spreading speed in every direction.
