OpenAI claim summary for Math-70

Summary of a claim published in openai/math; not a claim by this platform.
The main theorem exactly matches the boundary hypothesis and the complete action conclusion. Finite stabilizers/kernel are allowed in the record’s proper-action convention, so torsion is not silently removed. Within these assumptions, this is a claimed affirmative answer to the stated question.
Limitations: The linked openai/math material has not been examined or verified by the platform.

OpenAI's claim
OpenAI presents a proof in the selected manuscript. A hyperbolic group with two-sphere boundary is claimed to act geometrically on hyperbolic three-space with finite kernel.Mathematical statement of the claimed result
Result 1.
Let $G$ be word-hyperbolic with Gromov boundary $\partial G\cong S^2$. The source claims a homomorphism \[ \rho:G\longrightarrow\operatorname{Isom}(\mathbb H^3) \] whose action on hyperbolic three-space is proper and cocompact, and whose kernel is finite. With the additional assumption that $G$ is torsion-free, the corollaries identify $G\cong\pi_1(M)$, where $M$ is closed and has a hyperbolic metric in dimension three, and supply a finite-index subgroup \[ H\cong\pi_1(\Sigma)\rtimes\mathbb Z, \] where $\Sigma$ is a closed connected orientable surface. They also assert residual finiteness, virtual compact specialness, and positive virtual first Betti number in that torsion-free case.Outline of the argument
The argument applies a boundary modulus criterion. Unbounded modulus produces scalar limits analyzed by exponential records or subexponential probability flows; comparing same-depth expansions forces the required measure control and the three-dimensional hyperbolic action.Formal verification
For family 246, the documented theorem gives a proper cocompact hyperbolic-three-space action with finite kernel from the two-sphere boundary hypothesis.

OpenAI attributes these manuscripts to work by an internal model. Its release cautions that arguments without formalization can contain mistakes. This catalogue has not independently checked the proofs; the labels report the mathematical claims attributed to OpenAI.Sources
