Order-preserving maps of the Turing degrees: regularity and consistency strength

Liang Yu

We formulate a proof of Part~I of Martin's conjecture for order-preserving maps directly on the quotient of the reals by Turing equivalence. The assumptions are countable choice fo…

Small additive groups with $A + ξ A = R$

Liang Yu

We prove that, for every irrational $ξ$ , any $F_{σ}$ additive subgroup of $R$ has an $F_{σ}$ $\Q$-vector space extension of the same Hausdorff dimension satisfying $A + ξ A = R$ . Iteratio…
