Behavior of positive radial solutions for quasilinear elliptic equations [PDF]
We establish a necessary and sufficient condition so that positive radial solutions to − div ( A ( | ∇ u | ) ∇ u ) = f ( u ) , in

Refined asymptotics for constant scalar curvature metrics with isolated singularities
We consider the asymptotic behaviour of positive solutions u of the conformal scalar curvature equation, \Delta u + n(n-2)/4 u^{(n+2)(n-2) = 0, in the neighbourhood of isolated singularities in the standard Euclidean ball.

On a radial positive solution to a nonlocal elliptic equation
The paper deals with Dirichlet boundary value problem for the nonlinear Poisson equation with nonlocal term \[ - \Delta u = f (u, \int_U g \circ u) \] \[ u| _{\partial U} = 0, \] where \(U\) is assumed to be an annulus or a ball. Existence of solutions is obtained via fixed point theorems for increasing compact operators.

On the asymptotic shape of solutions to Neumann problems for non-cooperative parabolic systems
We consider a class of nonautonomous parabolic competition-diffusion systems on bounded radial domains under Neumann boundary conditions. We show that, if the initial profiles satisfy a reflection inequality with respect to a hyperplane, then global ...

Sign-changing bubble-tower solutions to fractional semilinear elliptic problems [PDF]
We study the asymptotic and qualitative properties of least energy radial sign-changing solutions to fractional semilinear elliptic problems of the form \[ \begin{cases} (-\Delta)^s u = |u|^{2^*_s-2-\varepsilon}u &\text{in } B_R, \\ u = 0 &\text{in ...

Increasing radial solutions for Neumann problems without growth restrictions
We study the existence of positive increasing radial solutions for superlinear Neumann problems in the ball. We do not impose any growth condition on the nonlinearity at infinity and our assumptions allow for interactions with the spectrum.
