ABSTRACT

S. Bulman-Fleming (Citation1992) presented necessary and sufficient conditions under which an amalgam of two copies of a monoid by a proper right ideal is flat, weakly flat, or principally weakly flat. In this note, a similar problem is considered for other generalizations of projective acts, namely for weak, Rees weak, and principal Rees weak projectivity.
