Title: Automorphisms no-where trivial of the Boolean algebra P(lambda) modulo the
ideal of the bouned subsets.

Abstract: We concentrate on an inaccessible cardinal (or aleph_0).
Juris Steprans and myself proved, assuming a instance
of GCH there is a non trivial automorphism.
We deal with having an automorphism which is
no-where trivial.
