Remarks on Halin's end-degree Conjecture

Gabriel Fernandes

We prove new instances of Halin's end degree conjecture (HC) in ZFC. In particular, we show that there is a proper class of cardinals kappa for which Halin's conjecture holds, answ…

Ray inflations of $ω_{1}$ -trees and ends of degree $ℵ_{1}$

Leandro Aurichi, Gabriel Fernandes, Paulo MagalhÃ£es JÃºnior +1

We prove the followings result for ray inflations of sparse graphs on $ω_{1}$ -trees. First, let $T$ and $S$ be pruned $ω_{1}$ -trees, let $G_{T}$ be a sparse $T$ -graph, and let $G_{S}$ be a…
