我们考虑二元模型,这是一个玩具模型,用于测试纳维-斯托克斯方程和欧拉方程的适定性和爆破问题。在相应的尺度范围内证明了粘性问题正解的适定性,该尺度范围对应于Navier-Stokes。同样地,当参数对应于非线性最强输运效应时,我们证明了无粘问题(在合适的正则类中)的适定性。
We consider the dyadic model, which is a toy model to test issues of well-posedness and blow-up for the Navier–Stokes and Euler equations. We prove well-posedness of positive solutions of the viscous problem in the relevant scaling range which corresponds to Navier–Stokes. Likewise we prove well-posedness for the inviscid problem (in a suitable regularity class) when the parameter corresponds to the strongest transport effect of the nonlinearity.
