I linked a paper by James Schmerl in a recent question which cites Karl Scherer, A Puzzling Journey to the Reptiles and Related Animals, Privately Published, 1987. I have had difficulty finding any mention of this document except for a lone citation on the Wikipedia page Rep-tile. I don't know if...

I am currently trying to find some field $F$ which includes $\mathbb{R}$ (or $\mathbb{C}$) and in which series $x^* = \sum_{i\in\mathbb{N}} x_i$ converge to some element of the field. (i.e. $x^* \in F$ whenever all $x_i \in F$) The hyper-real numbers seem like a promising candidate. I am ok wit...

In Classically verifiable quantum advantage from a computational Bell test, Kahanamoku-Meyer, Choi, Vazirani, and Yao propose using $x^2 \bmod N$ in an interactive proof-of-quantumness. This is a two-to-one function when $N$ is a semi-prime.. Of note, Kahanamoku-Meyer et al. emphasize that it is...
