Addendum to ``Maximal Chains in $\fomom$ and Ultrapowers of the Integers''
Saharon Shelah, Juris Steprāns
Upon presenting the proof of Theorem 3.3 in "Maximal chains in $$ and ultrapowers of the integers" I discovered that it is not entirely correct and certainly some details should be…
Dominating functions and graphs
Reinhard Diestel, Saharon Shelah, Juris Steprāns
A graph is called dominating if its vertices can be labelled with integers in such a way that for every function f: omega-> omega the graph contains a ray whose sequence of labels…
Somewhere trivial automorphisms
Saharon Shelah, Juris Steprāns
It is shown to be consistent that there is a non-trivial autohomeomorphism of beta N while all such autohomeomorphisms are trivial on some open set. The model used is one due to Ve…
Sums of Darboux and continuous functions
Juris Steprāns
It is shown that that for every Darboux function there is a non-constant continuous function such that is still Darboux. It is shown to be consistent --- the model us…
