### Nontrivial automorphisms of $\mathcal{P}(\mathbb{N})/ [\mathbb{N}]^{<\aleph_0}$ from variants of small dominating number

by Shelah and Steprans. [ShSr:990]

European J Math, 2015

It is shown that if various cardinal invariants of the
continuum related to d are equal to aleph_1 then
there is a nontrivial automorphism of {P}({N})/
[{N}]^{< aleph_0} . Some of these results extend to
automorphisms of {P}(kappa)/[kappa]^{< kappa} if
kappa is inaccessible
