Abstract

This paper develops a comprehensive geometric and homological framework for derived Gamma-geometry, extending the theory of commutative ternary Gamma-semirings established in our earlier works. Building upon the ideal-theoretic, computational, and categorical foundations of Papers A to D (Rao 2025A, Rao 2025B1, Rao 2025B2, Rao 2025C, Rao 2025D), the present study constructs the algebraic and geometric infrastructure necessary to place Gamma-semirings within the modern language of derived and categorical geometry. We define the affine Gamma-spectrum Spec_Gamma(T) together with its structure sheaf O_{Spec_Gamma(T)}, establishing a Zariski-type topology adapted to ternary Gamma-operations. In this setting, the category of Gamma-modules is shown to be additive, exact, and monoidal-closed, supporting derived functors Ext_Gamma and Tor^Gamma, whose existence is ensured through explicit projective and injective resolutions. The derived category D(T-Gamma-Mod) is then constructed to host homological dualities and Serre-type vanishing theorems, culminating in a categorical analogue of the Serre-Swan correspondence (Swan 1962, Gelfand 1960) for Gamma-modules. Geometric and categorical unification is achieved through fibered and derived Gamma-stacks, which provide a natural environment for studying morphisms of affine Gamma-schemes and cohomological descent. The theory connects with noncommutative geometry and higher-arity (n-ary) generalizations, showing that derived Gamma-geometry forms a coherent homological universe capable of expressing algebraic, geometric, and physical dualities within one categorical law. Computational methods for finite Gamma-semirings and applications to mathematical physics, where ternary operations model triadic couplings, are also discussed.

Normal Quaternionic Matrices and Finitely Generated Witt Rings

We present a new approach to verify the Elementary Type Conjecture for abstract Witt rings with small number of square classes. To do so, we make use of an abstract analogue of the 2-torsion part of the Brauer group. We develop a description of the entire structure of an abstract Witt ring with $2^n$ square classes in terms of a unique $n\times n$ matrix satisfying a small additional condition that particularly holds for Witt rings of fields. Via computational search, we find all these matrices for $n$ up to $7$. This verifies that all Witt rings of fields with up to $128$ square classes are of elementary type.

Graded differential polynomial rings

We study differential polynomial rings $R[t;δ]$ over $Γ$-graded rings, where $Γ$ is an arbitrary group. We show that $R[t;δ]$ admits a $Γ$-grading compatible with that of $R$ if and only if $δ$ is a $γ$-derivation for some $γ\in C_Γ(Γ_R)$, and that this grading is unique once $°(t)=γ$ is fixed; if $δ\neq0$, then $γ$ is itself uniquely determined by $δ$. We characterize the resulting graded ring by a universal property. We prove a characteristic-free center criterion for gr-simplicity whenever $Z(R[t;δ])$ is a graded subring; in characteristic zero, gr-simplicity is equivalent to $δ$-gr-simplicity of $R$ and $γ$-outerness of $δ$, extending Jordan's simplicity criterion to the graded setting. We further show that $R[t;δ]$ is gr-prime if and only if $R$ is $δ$-gr-prime, and that gr-Noetherianity of $R$ passes to $R[t;δ]$, recovering a graded Hilbert basis theorem as a special case. When $Γ$ is abelian, gr-simplicity and gr-primality are shown to be invariants of homogeneous graded Morita equivalence, and every ring homogeneously graded equivalent to $R[t;δ]$ via a compatible idempotent is again a graded differential polynomial ring.

Affinization of algebraic structures: Poisson algebras

An affinization of the notion of a Poisson algebra is presented. This is termed a Poisson affgebra and consists of an affine space together with an associative bi-affine multiplication and a bi-affine Lie bracket that acts as an affine derivation for the associative product. The constructive relation between Poisson affgebras and Poisson algebras is described and several low-dimensional examples are studied in detail.
