Mehdi Sadiq Abbas, Samir M. Saied · IOP Conference Series Materials Science and Engineering · 2020
Abstract Let M be a Γ-monoid and A a unitary right MΓ-act, two concepts projective and duo on gamma acts have been introduced. Several characterizations of projective and duo are given. We prove projectivity in gamma acts has dual basis using to prove relationship between duo and Γ-multiplication.
