This paper investigates the concept (σ, τ)- derivation on inverse Γ-semiring and extend a few results of this map on prime inverse Γ- semiring that acts as a homomorphism or as an anti- homomorphism, where σ, τ are automorphisms on M. 2023 2023 39 55 10.54216/GJMSA.0100105 https://www.americaspg.com/articleinfo/33/show/2403
