Turing complete stationary Euler flows on standard S^3 or T^3
Determine whether there exists a Turing complete stationary solution to the incompressible Euler equations on the round three-sphere (S^3, g_round) or on the flat three-torus (T^3, g_flat).
References
The following question remains unanswered: Does there exist a Turing complete stationary Euler flow on $(\mathbb S3,g_{round})$ or $(\mathbb T3,g_{flat})$?
