Remark on Regularity of Weak Solutions to the Navier-Stokes Equations.
The proof of some results published recently based on a classical theorem on compact operators. Weak solutions of the Navier-Sotkes equations in the space L2(O,T,W1,3(W)3) are regular....

Weak saturation and weak amalgamation property
We study the two model-theoretic concepts of weak saturation and weak amalgamation property in the context of accessible categories. We relate these two concepts providing sufficient conditions for existence and un...
