Uchida’s conjecture for open homomorphisms of Galois groups

Claimed, not checked 1 paper October 5, 2026
What the paper claims, in its own words

Proves Uchida's conjecture: every continuous open homomorphism between Galois groups of possibly infinite solvably closed Galois extensions of number fields comes from a unique equivariant field embedding in the opposite direction. No restriction on the kernel or separate cyclotomic-compatibility assumption is needed.
