We prove a bifurcation result of uniformly-rotating/stationary non-trivial vortex sheets near the circular distribution for a model of two irrotational fluids with same density taking into account surface tension effects. As bifurcation parameters, we play with either the speed of rotation, the surface tension coefficient or the mean vorticity.

  1. Long-time dynamics for the Kelvin-Helmholtz equations close to circular vortex sheets

    math.AP 2025-04 conditional novelty 8.0 of 10

    For almost all Weber numbers below 4(2+sqrt(3)), small-amplitude circular vortex sheets with surface tension stay O(ε)-close to the circular equilibrium for times of order ε^{-(N+1)} for every integer N.

  2. Two-dimensional capillary liquid drop: Craig-Sulem formulation on $\mathbb{T}^1$ and bifurcations from multiple eigenvalues of rotating waves

    math.AP 2025-05 conditional novelty 7.0 of 10

    For small angular momentum, there exists a unique rotation orbit of smooth rotating capillary drop solutions near the circle, built by a variational bifurcation argument from a multiple eigenvalue.
