Qualitative Behavior of Solutions to Cross-diffusion Systems from Population Dynamics

Abstract. A general class of cross-diffusion systems for two population species in a bounded domain with no-flux boundary conditions and Lotka-Volterra-type source terms is analyzed. Although the diffusion coefficients are assumed to depend linearly on the population densities, the equations are strongly coupled. Generally, the diffusion matrix is neither symmetric nor positive definite. Three ...

Population Dynamics of Iran from Sociological Approach

This paper examines intergenerational transmission associated with population dynamics from sociological approach. The discussion is based on the analysis of observations in a country that has experienced substantial changes in family formation resulting in one of the world's most spectacular falls in women's birth rate ever experienced in human history: Iran. Facing fundamental historical expe...

Qualitative Properties of Saddle-shaped Solutions to Bistable Diffusion Equations

We consider the elliptic equation −∆u = f(u) in the whole R , where f is of bistable type. It is known that there exists a saddleshaped solution in R. This is a solution which changes sign in R and vanishes only on the Simons cone C = {(x, x) ∈ R×R : |x| = |x|}. It is also known that these solutions are unstable in dimensions 2 and 4. In this article we establish that when 2m = 6 every saddle-s...

Special Session 3: Qualitative Behavior of Solutions to Evolutionary PDE’s

(λk(u), rk(u) being the k-th eigenvalue and a corresponding eigenvector of A(u)) is either the whole space or consists of a finite number of smooth, N−1dimensional, connected, manifolds that are transversal to the characteristic vector field rk. Relying on an adapted wave tracing method, we obtain the same tipe of error estimates valid for hyperbolic systems satisfying the classical assumptions...

from linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
