Let $\kappa$ be an uncountable cardinal with $\kappa=\kappa^{{\kappa^+$'' implies the statement "every closed subset of ${}^\kappa\kappa$ is a continuous image of ${}^\kappa(\kappa^+)$'' or its negation.

A Note on Symmetric Elements of Division Rings with Involution

Autor: Vo Hoang Minh Thu

Publikováno v: Acta Mathematica Vietnamica. 47:495-502

Let D be a division ring with involution ⋆ and S the set of all symmetric elements of D. Assume that the center F of D is uncountable and K is a division subring of D containing F. The main aim of this note is to show that S is right algebraic over

Borel’s conjecture and meager-additive sets

Autor: Daniel Calderón

Publikováno v: Proceedings of the American Mathematical Society. 149:4943-4954

We prove that it is relatively consistent with $\mathrm{ZFC}$ that every strong measure zero subset of the real line is meager-additive while there are uncountable strong measure zero sets (i.e., Borel's conjecture fails). This answers a long-standin
