Uncountably many non-rotationally symmetric type II ancient Yamabe flows on the sphere
Haixia Chen, Seunghyeok Kim, Monica Musso
For every , we construct uncountably many families of type II ancient solutions to the Yamabe flow on the unit round -sphere $\Ss^n$. These families are pairwise distin…
Stable blow-up on a sphere for a quadratic-derivative nonlinear wave equation
Manuel del Pino, Oliver Gough, Monica Musso
We study finite-time blow-up for the nonlinear wave equation \begin{equation*} v_{tt}-Îv=|\nabla_x v|^2 \end{equation*} in dimensions , under radial symmetry. For every pr…
Bifurcations in Isoperimetric Problems with Nonlocal Interactions
Fabio De Regibus, Massimo Grossi, Monica Musso
We study isoperimetric problems modeled on the liquid drop model, with nonlocal interactions under a volume constraint. While balls are natural critical points, we show that, for a…
Clustered vortex helices with compactly supported cross-sectional vorticity in the 3D Euler equations
Averkios Averkiou, Monica Musso, Fang Yu
We consider the three-dimensional incompressible Euler equations for helical flows without swirl. By adapting gluing techniques, we construct the first smooth multi-vortex solution…
