| Abstract: | For suitable groups  we will show that one can add a Boolean algebra  by forcing in such a way that  is almost isomorphic to  . In particular, we will give a positive answer to the following question due to J. Roitman: Is  a possible number of automorphisms of a rich Boolean algebra? |
