This paper defines contravariantly infinite subcategories of finitely generated modules over a commutative Noetherian ring and establishes several criteria for such infiniteness specifically in the case where the ring is a local complete intersection.
This paper addresses the point-wise and interval estimation of differential entropy for two normal populations under order-restricted prior information by deriving improved estimators that dominate the best affine equivariant estimator and comparing various confidence interval methods through numerical studies and a real-world application.
This paper investigates the complex reflection group associated with the octahedral group by determining its irreducible representations and character table, computing the modules of vector-valued invariants for each representation, and deriving explicit dimension formulas for the corresponding rings of invariants.
This paper establishes that for sufficiently large and , the maximum size of a 3-wise -intersecting family of -element subsets is , with the bound being asymptotically tight under the condition for .
This paper establishes the well-posedness of a complex -fractional Brownian bridge and proves the strong consistency and asymptotic distribution of its least squares parameter estimator for , revealing a unique two-dimensional limiting distribution with non-Cauchy marginals derived via complex Malliavin calculus.
This paper establishes a new sharp three-term inequality linking differential Rényi entropy, Rényi divergence, and Rényi cross-entropy for probability density functions, demonstrating that equality holds when one density is an escort of the other and using this result to derive further sharp bounds involving various informational functionals like absolute moments and Fisher information.
This paper introduces Drag-Aware Aerodynamic Manipulability (DAAM), a geometric framework for control allocation in redundant multirotors that utilizes a Riemannian metric to explicitly account for motor torque limits and aerodynamic drag, thereby generating a state-dependent manipulability volume that serves as a natural barrier function to optimize redundancy resolution while characterizing the resulting smooth manifolds and global jump discontinuities.
This paper develops a theory of asymptotic post-hoc inference that utilizes e-values to create sharper confidence sets and p-values with weaker assumptions than existing nonasymptotic methods, thereby allowing valid statistical conclusions even when significance levels are chosen after observing the data.
This paper investigates the primitive recursive analogue of computable categoricity spectra, demonstrating that these notions coincide for several natural classes of structures, including relatively -categorical equivalence structures and linear orders, relatively -categorical Boolean algebras, and computably categorical trees as partial orders.
This paper investigates the relationship between degrees of categoricity and their punctual (primitive recursive) analogues for functional structures, demonstrating that these notions coincide for non--categorical injection structures but diverge for certain -categorical ones, while also establishing the existence of specific PR-degrees with distinct properties in every non-zero c.e. Turing degree.
This paper introduces a matrix-based notion of matroid representation over local commutative rings using modular independence, establishing conditions under which this system forms a matroid, deriving structural properties for codes over chain rings, and demonstrating that certain non-field-representable matroids, such as the Vámos matroid, can be represented over rings like .
This paper establishes a natural -multicategory structure on moduli spaces of pseudo-holomorphic polygons to provide a uniform operadic framework for various -type structures, including Fukaya categories, as algebras over differential graded -multicategories.
This paper generalizes Zhou's 2021 recursion for a specific constant term identity—originally conjectured by Kadell and later proved by Károlyi, Lascoux, and Warnaar—by categorizing the variables into two parts to extend the result to a broader context.
This paper investigates the discrete-time Hawkes process by establishing its Large Deviation Principle, analyzing the limiting behavior of the associated arrival process, and demonstrating its application in modeling insurance claims.
This paper characterizes an agent's optimal consumption, investment, and time-varying job-switching strategies over a finite horizon by reducing the dual problem to a parabolic double obstacle problem with time-dependent obstacles, for which existence, uniqueness, and free boundary smoothness are rigorously established using PDE theory.
This paper proposes a coupling-aware wideband reconfigurable holographic surface (RHS) model and a Jacobian-aided WMMSE-based joint beamforming framework to maximize multi-user sum rate by effectively mitigating mutual coupling effects while satisfying practical power constraints, with its validity confirmed through Meep simulations and numerical experiments.
This paper introduces and systematically analyzes a variant of the Cops and Robbers game where a cop follows a predetermined patrol against an omniscient robber, determining the minimum capture radius required for various graph classes including trees, grids, and chordal graphs.
This paper generalizes Serre conjecture II to pseudo-reductive groups by proving its equivalence to the original conjecture for semisimple groups, thereby establishing that every torsor under a pseudo-semisimple, simply connected group over global function fields or non-archimedean local fields possesses a rational point.
This paper proves that, under a mild moment condition, the number of occurrences of a fixed rooted plane tree as a general subtree in a conditioned Galton--Watson tree is asymptotically normal with linear mean and variance, thereby confirming a conjecture by Janson and demonstrating that the result fails if the moment condition is violated.
This paper establishes a necessary and sufficient condition for embedding homogeneous quandles associated with a triplet into conjugation quandles, thereby generalizing existing results for Alexander quandles and providing new insights into core, Grassmann, and rotation quandles.
