Weak–strong uniqueness criteria for the critical quasi-geostrophic equation
We give two weak–strong uniqueness results for the weak solutions to the critical dissipative quasi-geostrophic equation when the initial data belongs to H ̇ − 1 / 2 . The first one shows that we can construct a unique H ̇ − 1 / 2 -solution when the initial data belongs moreover to L ∞ with a small...
