| Abstract: | This paper examines group automorphisms for which each element commutes with its image. These automorphisms do not necessarily form a subgroup of the automorphism group, but have a number of interesting properties, close to those of central automorphisms. Research of the first named author was supported by Grant SM 177 from Kuwait University Research Administration. |
