Titel: The Whitehead Problem and Suslin’s problem
Abstract: In this thesis I prove the independence of Whitehead’s problem in homological algebra And Suslin’s problem in order theory. In order to do this, I define the combinatorial principle ◊E , the diamond principle ◊ and Martin’s axiom, prove certain elementary consequences of these axioms, and use them in the independence proofs. I also discuss what these principles seem to say about the size of the set-theoretic universe.
