In this paper we use Grigorieff forcing to obtain the tree property at the second successor of a regular uncountable cardinal κ. We also show that Silver forcing can be used to obtain the tree property at ℵ2.

The paper reviews special Aronszajn trees, both at ω1 and κ+ for an uncountable regular κ. It provides a comprehensive classification of the trees and discusses the existence of these trees under different set-theoretical assumptions. The paper pr

Carbon and low-alloys steel components are used in various stages of steam power plants which are operating at elevated temperatures (up to 530°C). Long-term exposure of low-alloy steel components at elevated temperatures inevitably result in some k

We obtain an array of consistency results concerning trees and stationary reflection at double successors of regular cardinals $\kappa $ , updating some classical constructions in the process. This includes models of $\mathsf {CSR}(\kappa ^{++})\wedg

We show that the tree property, stationary reflection and the failure of approachability at $$\kappa ^{++}$$ are consistent with $$\mathfrak {u}(\kappa )= \kappa ^+ < 2^\kappa $$ , where $$\kappa $$ is a singular strong limit cardinal with the counta
