Ill-posedness of the 3D incompressible hyperdissipative Navier–Stokes system in critical Fourier-Herz spaces

Abstract: We study the Cauchy problem for the 3D incompressible hyperdissipative Navier-Stokes equations and consider the well-posedness and ill-posedness. We prove that if p > 6 8−α and q 1, the system is locally well-posed for large initial data as well as globally wellposed for small initial data. Also, we obtain the same result for p = 6 8−α and q ∈ [ 6 8−α , 2]. More importantly, we show that the system is ill-posed in the sense of norm inflation for p = 6 8−α and q > 2. The proof relies heavily on particular struc… Show more

“…For instance, the variable Herz spaces proved to be the key tools in the study of the regularity of solutions to elliptic equations by Scapellato [89], while Drihem [23,24] investigated semilinear parabolic equations with the initial data in Herz spaces or Herz-type Triebel-Lizorkin spaces. Also, the Fourier-Herz space is one of the most suitable spaces to study the global stability for fractional Navier-Stokes equations; see, for instance, [9,11,64,79]. Recently, Herz spaces prove crucial in the study of Hardy spaces associated with ball quasi-Banach function spaces in Sawano et al [88].…”

“…In the 1990's, the homogeneous Herz space ( Kβ,s u )(R n ) and the non-homogeneous Herz space (K α,p q )(R n ) are introduced by Lu and Yang [16]. In recent years, the homogeneous Herz space ( Kβ,s u )(R n ) and the non-homogeneous Herz space (K β,s u )(R n ) was investigated in harmonic analysis, see, [8,20,22]. For more research about Herz spaces in PDE and harmonic analysis, we refer to [3,10,19] and so on.…”

“…We refer readers to [7,19,20] and references therein. Beirao da Veiga [21,22] established an alternative type of criterion in terms of ∇u, which requires that ∇u ∈ L q ([0, T ]; L p (R 3 )) with 2 q…”
