### Failure of the Diagonal Argument

**Authors:** Wolfgang Mückenheim

**Comments:** 3 Pages.

It is shown that Cantor's diagonal argument fails because either there is no actual infinity and hence no defined diagonal number or there is actual infinity but the diagonal number cannot be distinguished from all real numbers of the Cantor list. Further it is shown by another argument that there are not uncountably many paths in the complete infinite Binary Tree.

### Set Theory or Slipper Animalcule: Who Wins?

**Authors:** Wolfgang Mückenheim

**Comments:** 3 Pages.

Limits of sequences of sets required to define infinite bijections do not only raise paradoxes but cause self-contradictory results.

Contrary to the assumptions of transfinite set theory, limit and union of infinite sequences of sets differ.
