Identification of diffusion coefficient in nonhomogeneous landscapes

摘要: Diffusion models have been found in various applications the study of spatial population dynamics for modeling species dispersal process natural environments. coefficient is a critical parameter diffusion equations. In this paper, new method estimating insects presented terms occupancy time and can produce any desired accuracy. The biological organism movement behaviors nonhomogeneous landscape investigating interplay between environmental heterogeneity movements. By constructing set eigenvalues, we characterize insect biased when crosses intersection two different type elements. Some numerical examples are provided to illustrate theoretical outcomes obtained paper.
