I work within the field of applied algebraic topology with main focus on different aspects of persistent homology and possible applications thereof. I will add a more detailed description at some point.

- It is well-known that both and are transcendental but it is not known whether and are irrational or not. Show that at most one of them is rational.
- Show that there exist irrational reals and such that
