Exactly one threshold bound state in every relative SU(N) BFSS model
OpenAI's claim
OpenAI presents a proof in the selected manuscript. For every finite $N\geq2$, the relative undeformed $SU(N)$ BFSS Hamiltonian is claimed to have exactly one square-integrable zero-energy state.Mathematical statement of the claimed result
Result 1.
For each $N\ge2$, use the gauge-invariant space $\mathcal H_N=[L^2(\mathbb R^{9(N^2-1)})\otimes\mathcal F_N]^{\operatorname{SU}(N)}$, with $\operatorname{Tr}(T_AT_B)=\delta_{AB}$, $[T_A,T_B]=if_{ABC}T_C$, and $\{\theta_\alpha^A,\theta_\beta^B\}=\delta_{\alpha\beta}\delta_{AB}$. The relative Hamiltonian closes the smooth invariant-core form \[ q_N(\Psi)=\frac1{16}\sum_\alpha\|Q_\alpha\Psi\|^2,\quad Q_\alpha=-i\partial_{iA}\gamma^i_{\alpha\beta}\theta_\beta^A +\tfrac12 f_{ABC}x_i^Bx_j^C\gamma^{ij}_{\alpha\beta}\theta_\beta^A. \] The asserted threshold-state count is \[ \dim\ker H_N=1. \] That kernel is $\operatorname{Spin}(9)$-invariant and even for the exterior grading whose polarization is $\gamma^1\gamma^2\gamma^3$, with the specified empty vector chosen even. The nine $\gamma^i$ are real symmetric $16\times16$ matrices with $\{\gamma^i,\gamma^j\}=2\delta_{ij}I$ and $\gamma^{ij}=\tfrac12[\gamma^i,\gamma^j]$. The space $\mathcal F_N$ is the irreducible complex Clifford module for $16(N^2-1)$ self-adjoint fermions, of dimension $2^{8(N^2-1)}$. The polarization's empty vector is the minimizer of $\tfrac i2\theta^{\mathsf T}(\gamma^1\gamma^2\gamma^3)\theta$; it is declared even, fixing the grading's sign.Outline of the argument
A massive deformation has a computable Fredholm index. Corrected profiles near separated centers and exterior estimates control the undeformed limit, while massive tightness prevents loss of states and the profile exhaustion fixes the kernel count after center-of-mass removal.Formal verification
Family 270 has no Lean scope page in this release. Its selected result is not presented as formalized. This site has not executed the Lean code. The scope descriptions do not certify the remaining manuscript arguments.Status caveat
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
