The conjecture on the -topology
The conjecture on the -topology
Let be a large field, and let the -topology denote the topology introduced in the paper. A topology is gt-henselian when it is a gt-henselian topology on .
The -topology conjecture. If is large, then the -topology is the intersection of all gt-henselian topologies on . Consequently, the -topology is a field topology if and only if there is a coarsest gt-henselian topology on .
For countable large fields this equivalence is known, while the conjecture asks for the general case.
