Big thank you! Very nice of you to share these references!

Thank you! Indeed, rather simple and natural an approach. Do you know, what ideas are there behind when chosing $\beta_1$ and alike?

comment Can one define informational content of a mathematical expression?
@AbdulhKhazzakGustavElFakiri: Nevertheless, the concept of encoding seems so much more obvious, when applied to strings, rather than exressions. Latter tend to have a complex underlying structure. Saying 1.0000.. is not the same as writing all the zeros, for example. Here you use a convention, that zeros continue.

comment Can one define informational content of a mathematical expression?
@AbdulhKhazzakGustavElFakiri: So, is it meaningful to assign the concept of information to an expression? And why does the informational content of an expression (seemingly compact) seem to differ so much from that of an irrational number (seemingly infinite)?

Dear @AbdulhKhazzakGustavElFakiri, your link is really interesting and somewhat relevant to my question. However, it is far from obvious to me, how exactly does it provide the answer. Can you please kindly state it more explicitly?

comment Links between difference and differential equations?
Mostly I am interested to know if it is possible to reformulate ones in terms of anothers, but more general possible studied relations would be also interesting.
