摘要 本⽂在实数域上的三维交换结合代数 T₃ 体系中,建⽴黎曼ζ函数的⼏何稳定性 框架,并通过场诱导黎曼度规的⽅法,给出黎曼猜想的完整归谬证明。 三维复数 T₃ 以 {1,e,i} 为基底,满⾜乘法公理 e²=1, i²=-1, ei=ie=0,⾃然诱导 符号差为 (+,-,+) 的 (2+1) 维闵可夫斯基背景度规。本⽂将标准黎曼ξ函数嵌⼊ 三维复数空间,构造三维函数 Ξ(σ,δ,t)=ξ(σ+it)·e^(δe),严格推导其分量展开、 零点等价条件与模⻓平⽅性质,给出兼容零点Hessian退化的稳定极⼩点定 义,并证明⾮退化情形下临界流形 Γ={(σ,δ,t)|σ=1/2} 的唯⼀性。 在此基础上,本⽂由模⻓平⽅泛函⾃⽣成场诱导黎曼度量,将零点分布问题转 化为流形上的极⼩曲⾯唯⼀性问题。利⽤函数⽅程带来的全局等距对称性,结 合凸泛函最⼩值集的连通性定理,严格证明全场仅存在唯⼀全局极⼩极值⾯ Γ。最终通过归谬法完成闭环:若存在⾯外零点,则必然破坏诱导度量的凸性 与对称性,导出⽭盾。本⽂完整证明所有⾮平凡零点均位于临界线 Re(s)=1/2 上,黎曼猜想成⽴。 关键词:黎曼猜想;三维复数;黎曼ξ函数;诱导黎曼度规;稳定极⼩流形;归 谬法;凸泛函最⼩值集连通性 Abstract This paper establishes a geometric stability framework for the Riemann zeta function within the three-dimensional commutative associative algebra T₃ over the real numbers, and provides a complete proof by contradiction of the Riemann Hypothesis via the method of field-induced Riemannian metrics. The 3D complex numbers T₃ have basis {1,e,i} satisfying the multiplication axioms e²=1, i²=-1, ei=ie=0, which naturally induce the (2+1)-dimensional Minkowski background metric with signature (+,-,+). This paper embeds the standard Riemann xi function into 3D complex space, constructing the 3D function Ξ(σ,δ,t)=ξ(σ+it)·e^(δe), rigorously deriving its component expansion, zero equivalence conditions, and squared-norm properties, giving a stability definition compatible with zero Hessian degeneracy, and proving uniqueness of the critical manifold Γ={(σ,δ,t)|σ=1/2} in the non-degenerate case. On this basis, this paper generates a Riemannian metric from the squared-norm functional itself, transforming the zero-distribution problem into a minimal- surface uniqueness problem on a manifold. Using the global isometry symmetry from the functional equation and the connectedness theorem for minimizer sets of convex functionals, we rigorously prove that globally there exists a unique global minimal extremal surface Γ . Finally, a proof by contradiction closes the loop: if an off-surface zero existed, it would necessarily break the convexity and symmetry of the induced metric, yielding a contradiction. This paper completely proves that all non-trivial zeros lie on the critical line Re(s)=1/2, establishing the Riemann Hypothesis.
