Steady states with unbounded mass of the Keller-Segel system
Angela Pistoia, Giusi Vaira
We consider the stationary Keller-Segel system from chemotaxis in a ball and we show the existence of a solution concentrating at the boundary of the ball.

Non-radial sign-changing solutions for the Schroedinger-Poisson problem in the semiclassical limit
Isabella Ianni, Giusi Vaira
We study the existence of nonradial sign-changing solutions to the Schroedinger-Poisson system in dimension N>=3. We construct nonradial sign-changing multi-peak solutions whose pe…
