Meaning of subsignatures | Babel Free

Examples

“In most cases, (thorn)-forking in T is equivalent to (thorn)-forking of algebraic closures in some T#95;i. This applies to fields with an action by (#92;mathbb#123;Q#125;,#43;), whose reducts to finite subsignatures are interdefinable with the theory of fields with one automorphism.”
