Singular solutions of perturbed logistic-type equations
We are concerned with the qualitative analysis of positive singular solutions with blow-up boundary for a class of logistic-type equations with slow diffusion and variable potential. We establish the exact blow-up rate of solutions near the boundary in terms of Karamata regular variation theory. This enables us to deduce the uniqueness of the singular solution. 2011 Elsevier Inc.

متن کاملsolutions of the perturbed klein-gordon equations
this paper studies the perturbed klein-gordon equation by the aid of several methods of integrability. there are six forms of nonlinearity that are considered in this paper. the parameter domains are thus identified.
متن کاملCounting solutions of perturbed harmonic map equations
In this paper we consider perturbed harmonic map equations for maps between closed Riemannian manifolds. In the case where the target manifold has negative sectional curvature we prove among other results that for a large class of semilinear and quasilinear perturbations, the perturbed harmonic map equations have solutions in any homotopy class of maps for which the Euler characteristic of the ...
متن کاملNumerical Solutions to Fractional Perturbed Volterra Equations
and Applied Analysis 3 where Θ is a weight function, is called the scalar product of functions f, g on the interval 0, t . Let us recall that two functions are orthonormal when ∀i,j 〈 φi t , φj t 〉 δij , 2.2 where δij is the Kronecker delta. We are looking for an approximate solution to 1.1 as an element of the subspaceHnφ , spanned on nφ first basic functions {φj : j 1, 2, . . . , nφ} unφ x, t...
متن کاملExistence and multiplicity of positive solutions for a coupled system of perturbed nonlinear fractional differential equations
In this paper, we consider a coupled system of nonlinear fractional differential equations (FDEs), such that both equations have a particular perturbed terms. Using emph{Leray-Schauder} fixed point theorem, we investigate the existence and multiplicity of positive solutions for this system.
