Symmetries, Hopf fibrations and supercritical elliptic problems
, 2015 We consider the semilinear elliptic boundary value problem \[ -\Delta u=\left\vert u\right\vert ^{p-2}u\text{ in }\Omega,\text{\quad }u=0\text{ on }\partial\Omega, \] in a bounded smooth domain $\Omega$ of $\mathbb{R}^{N}$ for supercritical exponents $p>\

Sign-changing blow-up for scalar curvature type equations [PDF]
, 2012 Given $(M,g)$ a compact Riemannian manifold of dimension $n\geq 3$, we are interested in the existence of blowing-up sign-changing families $(\ue)_{\eps>0}\in C^{2,\theta}(M)$, $\theta\in (0,1)$, of solutions to $$\Delta_g \ue+h\ue=|\ue|^{\frac{4}{n-2 ...

On Yamabe type problems on Riemannian manifolds with boundary
, 2015 Let $(M,g)$ be a $n-$dimensional compact Riemannian manifold with boundary. We consider the Yamabe type problem \begin{equation} \left\{ \begin{array}{ll} -\Delta_{g}u+au=0 & \text{ on }M \\ \partial_\nu u+\frac{n-2}{2}bu= u^{{n\over n-2}\pm\varepsilon} &

B-cell chronic lymphocytic leukaemia in an African lion (Panthera leo)
Veterinární Medicína, 2018 A 15-year-old female African lion (Panthera leo) maintained at the Zoological Garden of Pistoia, Tuscany (Italy), showed signs of malaise, dyspnoea, tremors, pale mucous membranes and ataxia for two days prior to death.

Multiple blow-up phenomena for the sinh-Poisson equation
, 2012 We consider the sinh-Poisson equation $$(P)_\lambda\quad -\Delta u=\la\sinh u\ \hbox{in}\ \Omega,\ u=0\ \hbox{on}\ \partial\Omega,$$ where $\Omega$ is a smooth bounded domain in $\rr^2$ and $\lambda$ is a small positive parameter. If $0\in\Omega$ and $\

Large mass boundary condensation patterns in the stationary Keller-Segel system [PDF]
, 2016 We consider the boundary value problem $-\Delta u + u =\lambda e^u$ in $\Omega$ with Neumann boundary condition, where $\Omega$ is a bounded smooth domain in $\mathbb R^2$, $\lambda>0.$ This problem is equivalent to the stationary Keller-Segel system ...

Zoo Biology, EarlyView.We investigated the extent and composition of red panda (Ailurus Fulgens spp.) encounters amongst 150 global zoos and their impact on animal longevity and reproduction. Comparative data analysis suggests that encounter animals produced more offspring and had higher longevity (survival) than non‐encounter animals with differences noted between ...

Multi-bubble nodal solutions for slightly subcritical elliptic problems in domains with symmetries
, 2012 We study the existence of sign-changing solutions with multiple bubbles to the slightly subcritical problem $$-\Delta u=|u|^{2^*-2-\e}u \hbox{in}\Omega, \quad u=0 \hbox{on}\partial \Omega,$$ where $\Omega$ is a smooth bounded domain in $\R^N$, $N\geq 3$,

Sign-changing solutions to elliptic second order equations: glueing a peak to a degenerate critical manifold [PDF]
, 2014 We construct blowing-up sign-changing solutions to some nonlinear critical equations by glueing a standard bubble to a degenerate function. We develop a method based on analyticity to perform the glueing when the critical manifold of solutions is ...
