Oct 8, 2023 at 18:10 | comment | added | David Feldman | In general a path in ordered-zero-set space space that induces a permutation on the zeros, so a loop in unordered-zero-set space will drag along an discrete invariants attached to the zeros. | |
Oct 8, 2023 at 16:41 | comment | added | David Feldman | If you have a tie between the modulus of two zeros, then a perturbation could flip how they stand in the order, causing a discontinuity in the choice of elementary factors, right? | |
Oct 7, 2023 at 18:51 | comment | added | Vik78 | I don't see why the Weierstrass factorization theorem can't apply in a canonical way. You can just choose an ordering on the zero set in order of nondecreasing modulus, and choose your elementary factors $E_{p_n}$ with $p_n = n$. See Conway, Functions of One Complex Variable, theorems VII.5.12 and VII.5.15. For whatever natural complex structure you choose on the spaces involved I expect this section would be analytic. | |

Oct 5, 2023 at 17:00 | comment | added | David Feldman | I was trying not to be too specific in case someone knew a relevant theorem. But I'd be happy with the Hausdorff metric. I'd be happy with considering first sequences, considering them in the product (topology) of countably many disks, then taking a quotient by the action of the full symmetric group. | |
