The full nonvanishing result for twisted elliptic transfer

Let E/FE/F be the quadratic extension, let nur \mathfrak{n}_{\mathrm{ur}} denote the unramified part of the relevant conductor n \mathfrak{n}, and let ω\omega be a character of E×E^\times. The subgroup (1+nurDE/F)OE×(1+\mathfrak{n}_{\mathrm{ur}}\mathfrak{D}_{E/F})\cap\mathcal{O}_E^\times is defined using the different DE/F\mathfrak{D}_{E/F} of E/FE/F. The full nonvanishing conjecture. Corollary should hold for all ω\omega that are trivial on

(1+nurDE/F)OE×.(1+\mathfrak{n}_{\mathrm{ur}}\mathfrak{D}_{E/F})\cap\mathcal{O}_E^\times.

This is presented as the expected extension of the preceding result, which proves the corollary only under additional conditions on n\mathfrak{n}; the full assertion remains unresolved in the supplied text.
