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}^+).

Policy Iteration Achieves Regularized Equilibrium under Time Inconsistency

This paper proposes a policy iteration algorithm for general entropy-regularized time-inconsistent stochastic control problems that converges exponentially to an equilibrium policy by proving the generated value functions form a Cauchy sequence, thereby establishing the global existence and uniqueness of a classical solution to the associated exploratory equilibrium Hamilton–Jacobi–Bellman equation.

Alkaid: Resilience to Edit Errors in Provably Secure Steganography via Distance-Constrained Encoding

The paper proposes Alkaid, a provably secure steganographic scheme that achieves deterministic robustness against edit errors by integrating minimum distance decoding into the encoding process, thereby significantly outperforming state-of-the-art methods in decoding success rates, payload capacity, and encoding speed.

On the Secrecy Performance of Continuous-Aperture Arrays Over Fading Channels

This paper analyzes the secrecy performance of continuous-aperture array (CAPA) systems over Rayleigh fading channels, deriving theoretical expressions for secrecy rate and outage probability across single, multiple independent, and multiple collaborative eavesdropper scenarios, and demonstrating that CAPA systems outperform traditional spatially-discrete arrays by achieving higher secrecy rates, lower outage probabilities, and a diversity order equal to the spatial degrees of freedom.
