Derived Functors, Resolutions, and Homological Dualities in n-ary Gamma-Semirings
Abstract
This paper develops the homological backbone of the theory of non-commutative n-ary -semirings. Starting from an n-ary -semiring (T,+,μ) and its -ideals, we work in the slot-sensitive categories of left, right, and bi--modules, and endow the bi-module category with a Quillen exact structure compatible with the n-ary multiplication. Within this exact framework we construct bar-type projective resolutions and cofree-based injective resolutions under natural -Noetherian and -regular hypotheses on T, and we obtain finite projective resolutions for finitely presented bi-modules under -Noetherian conditions. On this basis we define the derived functors and for bi--modules, prove their balance with respect to projective and injective resolutions, establish long exact sequences and a Yoneda interpretation via iterated extensions, and construct K\"unneth-type spectral sequences and base-change isomorphisms. Interpreting bi--modules as quasi-coherent sheaves on the non-commutative -spectrum T, these homological invariants provide the appropriate derived language for a non-commutative -geometry and prepare the ground for the spectral and geometric analysis carried out in the third part of this series.
