Read the background

Every continuous open homomorphism between the Galois groups of solvably closed Galois extensions of number fields is induced by a unique equivariant field embedding in the opposite direction, without a kernel restriction.

Why it matters

If correct, proves Uchida’s full open-homomorphism conjecture for these global Galois groups.

What counts as progress

Does every continuous open homomorphism of the stated global Galois groups come from a field embedding?
