The interesting thing with the slog is, that new branchpoints come into existence on different branches (which then create new branches), which you can see in Dmitriis plot.
I am not sure whether anyone has a complete description of this infinitely nested structure.
At least we can say that there must be infinitely many branchpoints of the slog, because each branch point \( z \) occurs again at \( z+2\pi i k \) for all integer \( k \).
\( \operatorname{slog}(z+2\pi i k)=\operatorname{slog}(e^{z + 2\pi i k })-1=\operatorname{slog}(z) \).
However they dont need to occur on the same branch, but they must occur on some branch.
And I never heard about anyone considering the branchpoint structure of sexp at \( z\le -2 \).
