Existence and nonexistence of radial positive solutions of superlinear elliptic systems [PDF]
, 2001 The main goal in this paper is to prove the existence of radial positive solutions of the quasilinear elliptic system [formula], where [omega] is a ball in RN and f, g are positive continuous functions satisfying f(x, 0, 0) = g(x, 0, 0) = 0 and some ...

On the positive, “radial” solutions of a semilinear elliptic equation in N$\mathbb {H}^N$
Advances in Nonlinear Analysis, 2012 We discuss various kinds of existence and non existence results for positive solutions of Emden–Fowler type equations in the hyperbolic space. The main tools are perturbation analysis, variational methods, Pohozeav type identities and reduction to ...

Radial basis function based meshless methods for fluid flow problems
, 2006 This thesis is concerned with the development of meshless methods using radial basis functions for solving fluid flow problems. The advantage of meshless methods over traditional mesh-based methods is that they make use of a scattered set of collocation ...

Positive radial solutions for systems with mean curvature operator in Minkowski space [PDF]
, 2017 We are concerned with a Dirichlet system, involving the mean curvature operator in Minkowski space M(w) = div (∇w / 1−|∇w|2) in a ball in RN. Using topological degree arguments, critical point theory and lower and upper solutions method, we obtain non ...

Positive radial solutions for a class of quasilinear Schrödinger equations in R3 [PDF]
, 2022 This paper is concerned with the following quasilinear Schrödinger equations of the form: −∆u − u∆(u 2 ) + u = |u| p−2u, x ∈ R 3 where p ∈ (2, 12). By making use of the constrained minimization method on a special manifold, we prove that the existence of
