On radial two-species Onsager vortices near the critical temperature
Tonia Ricciardi, Ryo Takahashi
We compare two mean field equations describing hydrodynamic turbulence in equilibrium, which are derived under a deterministic vs.\ stochastic assumption on the variable vortex int…
A multi-species chemotaxis system: Lyapunov functionals, duality, critical mass
Nikos I. Kavallaris, Tonia Ricciardi, Gabriella Zecca
We introduce a multi-species chemotaxis type system admitting an arbitrarily large number of population species, all of which are attracted vs. repelled by a single chemical substa…
Existence of stationary turbulent flows with variable positive vortex intensity
Francesca De Marchis, Tonia Ricciardi
We prove the existence of stationary turbulent flows with arbitrary positive vortex circulation on non simply connected domains. Our construction yields solutions for all real valu…
Sign-changing tower of bubbles for a sinh-Poisson equation with asymmetric exponents
Angela Pistoia, Tonia Ricciardi
Motivated by the statistical mechanics description of stationary 2D-turbulence, for a sinh-Poisson type equation with asymmetric nonlinearity, we construct a concentrating solution…
Minimal blow-up masses and existence of solutions for an asymmetric sinh-Poisson equation
Tonia Ricciardi, Gabriella Zecca
For a sinh-Poisson type problem with asymmetric exponents of interest in hydrodynamic turbulence, we establish the optimal lower bounds for the blow-up masses. We apply this result…
Sign-changing two-peak solutions for an elliptic free boundary problem related to confined plasmas
Giovanni Pisante, Tonia Ricciardi
By a perturbative argument, we construct solutions for a plasma-type problem with two opposite-signed sharp peaks at levels and , respectively, where . We establish…
