The breadth of constructibility degrees and definable Sierpiński's coverings
Alessandro Andretta, Lorenzo Notaro
Generalizing a result of Törnquist and Weiss, we study the connection between the existence of Sierpiński's coverings of , and a cardinal invariant of…
Linear orders: when embeddability and epimorphism agree
Riccardo Camerlo, Raphaël Carroy, Alberto Marcone
When a linear order has an order preserving surjection onto each of its suborders we say that it is strongly surjective. We prove that the set of countable strongly surjective line…
Cardinal characteristics at κ in a small u(κ) model
A. D. Brooke-Taylor, V. Fischer, S. D. Friedman +1
We provide a model where u(κ) < 2^κ for a supercompact cardinal κ. Garti and Shelah have provided a sketch of how to obtain such a model by modifying the construction in a paper of…
Killing the GCH everywhere with a single real
Sy David Friedman, Mohammad Golshani
Shelah-Woodin investigate the possibility of violating instances of through the addition of a single real. In particular they show that it is possible to obtain a failure of…
Representations of ideals in Polish groups and in Banach spaces
Piotr Borodulin-Nadzieja, Barnabas Farkas, Grzegorz Plebanek
We investigate ideals of the form is unconditionally convergent , where is a sequence in a Polish group or in a Banach…
