Parallel algorithm for matroid basis computation with O(n^{1/3} log^{1/3} n) round complexity, nearly matching the KUW lower bound.
A Master Theorem supplies explicit formulas for topological zeta functions of matroids and solves multiple conjectures.
A threshold κ=Θ(1/√α) (α=m/n) separates easy collision finding from OGP-based exponential lower bounds against online algorithms in single-layer binary NNs.
PAL uses the classical Preisach hysteresis operator with learned thresholds and an extrema stack to model sequences, proving O(1)-depth Turing completeness via two-stack PDA simulation and incomparability with standard transformers on rate-independent vs. random-access functions.
Categorical univalence of a universe does not entail function extensionality, as shown by polynomial models of type theory that refute the latter while satisfying the former.
Vitriflow is a new explicit calibration framework for melt-quench MD that produces statistically converged, screened amorphous ensembles demonstrated on a-SiO2, a-Si3N4 and a-Sm2O3.
Introduces separable and essentially separable graphs as a broad class for mixed graphical models, provides multiple characterizations of the graphs and their separation equivalence, and develops an identification algorithm for equivalence classes.
In the subcritical regime m = m_c(1-ε) with ε→0 and ε³n→∞, the largest component L1 satisfies L1 = (1+o_p(1)) * [2(α+2)/(α+1)] ε^{-2} log(ε³ n) for fixed α>0 (and analogous limits when α(n)→a).
Classifies finite-field Clifford dual-unitary gates into q-2 perfect-tensor cores and others, deriving exact masking distances d1(t)=4t and d2(t)=4t-2 for perfect-tensor circuits.
Sound and complete axiomatizations are provided for path-reachability logic with Cantor derivative in T1 topologies and metric spaces, with decidability via neighborhood semantics that yields the finite model property.
Introduces direct belief contraction on unconstrained Kripke models in DEL, shows it satisfies some but not all contraction properties, and gives sound complete axiomatizations for the logic and its extension to private announcements.
Quantum corrections suppress the symmetron fifth force by order 10% within a Compton wavelength of a thick planar source and enhance it at larger distances.
Unifilarisation of stochastic Mealy machines is an instance of coalgebraic determinisation over monads with support structure, producing causal stochastic behaviours rather than Moore-style output distributions.
Mazur and Jester manifolds have pairwise nonhomeomorphic boundaries via an octahedral hyperbolic structure, Dehn filling, and systolic geodesics, distinguishing their contractible 4-manifolds.
Seiberg-Witten instanton expansions combined with exact WKB period integrals allow analytic computation and continuation of quasinormal modes from large q to q=0.
An active learning method based on E-SINDy identifies governing ODEs and PDEs accurately with significantly fewer data samples than random sampling across tested systems.
Effective scalaron-photon coupling in f(R) gravity vanishes in the light-scalaron limit due to cancellation of anomaly-induced and diagrammatic contributions.
Provides algorithms and complexity results for the δ-Dispersion and δ-Covering problems on bounded-treewidth graphs for integer, rational, and irrational distances.
Diagonal EP under variance-profile Gaussian matrices produces Gaussian-process dynamics with profile-dependent memory instead of conventional scalar state evolution.
LSD extends speculative sampling to second-order Langevin dynamics, achieving 3-9x speedup in MD while exactly sampling from the target distribution without relative error.
Introduces Δ-VFE pivoted Cholesky, a pivot rule maximizing the one-step gain in a VFE functional for kernel matrices via closed-form decomposition and batch sampling, yielding improved GP objective values and accuracy at low ranks.
DAML is a new dynamic modal logic that derives conditional obligations in multi-agent settings by combining action models with deontic value maximization over outcomes.
Training-language dominance, not English inherent properties, determines brain-LLM alignment across English, Chinese, and French, with additional independent effects from typological distance concentrated in syntactic brain regions.
