Oort's conjecture on automorphisms of generic supersingular abelian varieties

This paper proves Oort's conjecture that the automorphism group of a generic principally polarized supersingular abelian variety in characteristic pp is {±1}\{\pm 1\}, except for the specific cases of genus 2 or 3 with p=2p=2, while also providing an explicit description of the a=1a=1-locus in the corresponding Rapoport-Zink space and establishing analogous results for supersingular pp-divisible groups.

A Hierarchical Bayesian Dynamic Game for Competitive Inventory and Pricing under Incomplete Information: Learning, Credible Risk, and Equilibrium

This paper proposes a hierarchical Bayesian dynamic game framework for competitive inventory and pricing under incomplete information, integrating Bayesian learning, strategic belief updating, and a credible-risk criterion to derive a conservative equilibrium that effectively balances profit maximization with uncertainty management.

Operators arising from invariant measures under some class of multidimensional transformations

This paper investigates a linear operator derived from invariant measures under multidimensional transformations, using its iterates to provide an explicit solution for the associated functional equation and to establish the existence of absolutely continuous invariant measures that generalize classical pp-adic maps to higher dimensions.

Distributed Semantic Alignment over Interference Channels: A Game-Theoretic Approach

This paper proposes a distributed non-cooperative game-theoretic framework for jointly optimizing linear MIMO transceivers to resolve semantic mismatches and mitigate multi-user interference in goal-oriented communication systems, deriving a closed-form Nash Equilibrium that balances information compression, interference management, and task performance.

BPS and semi-BPS kink families in two-component scalar field theories with fourth-degree polynomial potentials

This paper systematically investigates kink solutions in two-component scalar field theories with quartic potentials using the Bogomolny formalism, demonstrating that generalized superpotentials yield new models featuring continuous families of composite kinks with nontrivial internal structures.

Qualitative properties of the fractional magnetic pp-Laplacian and applications to critical quasilinear problems

This paper establishes the functional framework and existence of weak solutions for quasilinear equations involving the fractional magnetic pp-Laplacian in three dimensions by employing variational methods and introducing a novel concentration compactness principle to address challenges posed by nonlocality, magnetic potentials, and critical nonlinearities.

Green currents of holomorphic correspondences on compact Kähler manifolds

This paper constructs Green currents associated with the dominant eigenspaces of holomorphic correspondences on compact Kähler manifolds under specific dynamical degree conditions, establishes the log-Hölder continuity of their super-potentials, and proves the exponential equidistribution of positive closed currents toward the main Green current when the correspondence exhibits simple cohomological action and satisfies a local multiplicity assumption.

Rubio de Francia Extrapolation Theorem for Quasi non-increasing Sequences

This paper establishes the discrete Rubio de Francia extrapolation theorem for pairs of quasi non-increasing sequences with QBβ,p\mathcal{QB}_{\beta, p} weights and provides a weight characterization for the boundedness of the generalized discrete Hardy averaging operator on such sequences within the space lwp(Z+)l_w^p(\mathbb{Z}^+).
