OpenAI reports filtered-product nullity from complex cobordism

  • Mathematics

For a finite pointed CW pair G ⊂ E and based map v:E→Sᵈ whose restriction to G becomes null after passage to complex cobordism, the restriction of a sufficiently large smash power v∧ℓ to the union where any fixed positive fraction of factors lie in G is stably null. The paper also derives a boundary-preserving cube compression theorem from a torus-slot bundle embedding of rank strictly below twice the source rank.

OpenAI reports arithmetic classification of twisted lattice-factor correspondences

  • Mathematics

For an ICC group commensurable with a lattice in a finite product of the specified property-(T) algebraic groups over characteristic-zero local fields, any countably infinite ICC comparison group, and arbitrary normalized scalar cocycles at both ends, every bifinite correspondence between their twisted group factors is a closed bimodule summand of a finite sum of models from finite-index subgroup isomorphisms and finite-dimensional projective representations of the matched cocycle ratio. Conversely, every such model, sum, and closed summand is bifinite.

OpenAI reports local conformal symmetry from scale symmetry in a four-dimensional QFT class

  • Mathematics
  • Theoretical Physics

Under Assumption 2.1 for a four-dimensional local, unitary, positive-energy vacuum QFT—with a physical local stress tensor and dilatation current, discrete bounded-below finite-multiplicity scaling spectrum, finite scaling support of each original field, and compatible affiliated fields in a causally commuting bounded local net—the stress tensor admits a physical dimension-two scalar improvement that is symmetric, conserved, and traceless without changing translation or Lorentz charges. Its conformal currents obey unbroken local Ward identities on the physical field algebra.

OpenAI reports generic weak future inextendibility near rotating Kerr

  • Mathematics
  • Theoretical Physics

For each fixed subextremal rotating Kerr bridge (M > 0 and 0 < |a| < M), smooth vacuum data in a sufficiently small weighted tenth-order neighborhood whose full maximal globally hyperbolic development admits a future continuous, nondegenerate Lorentzian extension with locally square-integrable weak connection form a meagre set. Hence inextendible data are residual in the weighted smooth topology.

OpenAI reports classwise permanence for weakly reversible mass-action systems

  • Mathematics

For every finite weakly reversible mass-action network with fixed positive rates, each positive stoichiometric compatibility class has one compact convex forward-invariant set entered eventually by every positive trajectory in that class, including when the class is unbounded.

OpenAI reports an FPRAS for common integer polymatroid bases

  • Mathematics
  • Theoretical Computer Science

With exact rank-value oracles, the number of common integer bases of two equal-rank polymatroids can be approximated by an FPRAS whose oracle calls and non-oracle bit work are polynomial on every run in ground-set size, binary input length, inverse relative error, and log inverse failure probability.

OpenAI reports uniqueness of first-time surface mean-curvature tangents

  • Mathematics

At every singular point of the first singular time for the mean-curvature flow of a smooth compact connected embedded surface in R³, the full fixed-center rescaling family converges locally smoothly on compact negative-time intervals to one multiplicity-one homothetic self-shrinker in the original ambient coordinates.

OpenAI reports height-two Hahn–Wilson counterexamples

  • Mathematics

For every sufficiently large prime p, a connective p-complete spectrum of exact fp-type two lies outside the ordinary thick subcategory generated by the specified standard BP⟨2⟩ p-completion, even though its finite and telescopic localization comparisons hold.

OpenAI reports a boundary obstruction to four-dimensional disk embedding

  • Mathematics

A compact oriented smooth four-manifold contains finitely many immersed disk maps with framed algebraic dual spheres whose embedded boundary circles bound no pairwise disjoint proper locally flat disks, even without prescribed output homotopy classes or framings.

OpenAI reports approximation paving for every maximal abelian subalgebra

  • Mathematics

For every maximal abelian subalgebra of a complex von Neumann algebra, every self-adjoint operator is a strong-operator limit of self-adjoint approximants of norm at most three times its norm, each admitting norm paving to relative error ε with at most Cε⁻⁶ projections for a universal C.

OpenAI reports polynomial unitary synthesis with a Boolean oracle

  • Theoretical Computer Science

For every n, one quantum oracle circuit generated in polynomial time from n using H, T, T† and CNOT approximates the channel of every n-qubit unitary to full diamond-norm error at most 1/2 after a suitable Boolean oracle is chosen; circuit size, qubits, queries and query length are polynomial in n.

OpenAI reports a Coulomb density without Kohn–Sham ensemble representation

  • Mathematics
  • Theoretical Physics

A finite three-electron molecule with two equal positive integer nuclear charges has a normalizable interacting Coulomb ground state whose spin-summed density is not the density of any noninteracting ground-state ensemble for a single real spin-independent local potential in L^(3/2)(R³)+L∞(R³).

OpenAI reports bounded klt complements for Fano contractions

  • Mathematics

For each fixed dimension d and positive rational epsilon, every epsilon-log-canonical Fano contraction of a normal integral variety over an algebraically closed characteristic-zero field admits, near each closed base point, a klt complement whose Cartier index is bounded only by d and epsilon.

OpenAI reports orbifold Iitaka subadditivity

  • Mathematics

For a surjective connected-fiber holomorphic map from a smooth compact connected Fujiki-class-C manifold with rational simple-normal-crossing boundary to a normal compact irreducible complex space, the total log Kodaira dimension is at least the sum of the very general fiber log Kodaira dimension and Campana’s orbifold-base Kodaira dimension, including boundary coefficient one.

OpenAI reports integral density on curve character varieties

  • Mathematics

For every smooth connected complex algebraic curve, every rank r, and prescribed quasi-unipotent boundary conjugacy classes, including nonsemisimple classes, one finite extension of the number field generated by their eigenvalues makes ambient integral points Zariski dense in the exact-boundary locus of the SL_r character variety and in every irreducible component.

OpenAI reports a joint Ashkin–Teller height-and-current limit

  • Mathematics
  • Theoretical Physics

At every fixed point on the critical Ashkin–Teller line, including the four-state Potts endpoint, the height and both current-cluster collections converge jointly in bounded Jordan domains: the height to a Gaussian free field and the clusters to canonical recursive two-valued local sets of that field, including all nesting depths and the wired boundary cluster.

For each fixed edge-change weight x∈[1/√2,1], zero-boundary integer Lipschitz heights on triangular-lattice inside approximations of a bounded C² Jordan domain converge, after division by a positive x-dependent constant, to the zero-Dirichlet Gaussian free field as a random distribution.
