| Aug 7, 2019 at 12:15 | comment | added | Andrea Marino | If I am not wrong, you are using that the cardinal is infinite. Using monotonicity in the base, in this case you have $2^{\aleph} <= (\aleph)^{\aleph} <= (2^{\aleph})^{\aleph} = 2^{\aleph \times \aleph} = 2^{\aleph}$ so that the bound is the same (I haven't checked the proof yet). | |
