Self-Similar Solutions of the Two-Dimensional Incompressible Euler Equation from Large Initial Data

Hyungjun Choi

Let $0 < a < 1$ and let $u_{0}$ be a $C^{1}$ , divergence-free, $(- a)$ -homogeneous vector field on $R^{2} ∖ {0}$ . We construct a forward-in-time self-similar solution of the…

Multi-Sink Solutions to the Self-Similar Euler Equations

Hyungjun Choi, Matei P. Coiculescu

We construct examples and provide a classification of self-similar solutions to the two-dimensional incompressible Euler equations whose pseudo-velocity fields possess more than on…

Asymmetric Self-similar Spiral Solutions of 2-D Incomressible Euler Equations

Hyungjun Choi

We construct nonradial, self-similar solutions to the two-dimensional incompressible Euler equations without assuming rotational symmetry. These solutions extend the study of self-…
