Everted equilibria of a spherical cap : a singular perturbation method
The example is constructed of the C1-smooth skew product of interval maps possessing the one-dimensional ramified continuum (containing no arcs homeomorphic to the circle) with an infinite set of ramification points as the global attractor.
The system of nonlinear differential equations is under consideration, where and are positive constants and and are positive continuous functions on . There are three types of different asymptotic behavior at infinity of positive solutions of (). The aim of this paper is to establish criteria for the existence of solutions of these three types by means of fixed point techniques. Special emphasis is placed on those solutions with both components decreasing to zero as , which can be...
We provide existence and stability results for semilinear Dirichlet problems with nonlinearities satisfying some general local growth conditions. We derive a general abstract result which we then apply to prove the existence of solutions, their stability and continuous dependence on parameters for a sixth order ODE with Dirichlet type boundary data.
We solve the problem of the existence and uniqueness of coexistence states for the classical predator-prey model of Lotka-Volterra with diffusion in the scalar case.
We give existence theorems for weak and strong solutions with trichotomy of the nonlinear differential equation where is a family of linear operators from a Banach space into itself and . By we denote the space of linear operators from into itself. Furthermore, for and , we let be the Banach space of continuous functions from into and . Let be a strongly measurable and Bochner integrable operator on and for define for each . We prove that, under certain conditions,...
