My mathematically-oriented work generally explores discrete geometric and probabilistic themes in physics, computation, and communication. Jack of most trades, master of none.

comment Smooth bivariate functions identifiable under permutations
For $f$ symmetric and otherwise nice you may want to consider it as a graphon, cf. people.math.osu.edu/glasscock.4/graphons.pdf

comment Regular epimorphisms in the category of simple undirected graphs
@DominicvanderZypen -- It doesn't answer the question: it merely reinforces Todd's comment and gives context along those lines.

comment Decidability of $x^3+y^3+z^3 = c$
The latest relevant reference seems to be Elsenhans, A.-S. and Jahnel, J. "New sums of three cubes". Math. Comp. 78, 1227 (2009).

comment Decidability of $x^3+y^3+z^3 = c$
Poonen's article "Undecidability in number theory" begins: "Does the equation $x^3+y^3+z^3 = 29$ have a solution in integers? Yes: $(3, 1, 1)$, for instance. How about $x^3+y^3+z^3 = 30$? Again yes, although this was not known until 1999: the smallest solution is $(−283059965, −2218888517, 2220422932)$. And how about $x^3+y^3+z^3 = 33$? This is an unsolved problem."

This is more for physicists but nevertheless looks like it should be pretty insightful: arxiv.org/abs/1410.3831

comment When few simple conditions yield a unique intricate structure
It is worth pointing out that two of your examples (j-invariant and sporadic simple groups) are related through moonshine, as is the intricate structure of the Golay code.

comment How can we interpret the eigenvalues and eigenvectors of Euclidean Distance Matrices?
In this case PCA is functionally equivalent to metric multidimensional scaling. The latter, however, works directly on the distance matrix.
