Abstract

In this paper, we initiate the study of algebraic K-theory for non-commutative Γ\Gamma-semirings, extending the classical constructions of Grothendieck and Bass to this setting. We first establish the categorical foundations by constructing the category of finitely generated projective bi-Γ\Gamma-modules over a non-commutative Γ\Gamma-semiring TT. We prove that this category admits an exact structure, allowing for the definition of the Grothendieck group K0Γ(T)K_0^\Gamma(T). Furthermore, we develop the theory of the Whitehead group K1Γ(T)K_1^\Gamma(T) using elementary matrices and the Steinberg relations in the non-commutative Γ\Gamma-semiring context. We establish the fundamental exact sequences linking K0K_0 and K1K_1 and provide explicit calculations for specific classes of non-commutative Γ\Gamma-semirings. This work lays the algebraic groundwork for future studies on higher K-theory spectra.
