Kernel Based Maximum Entropy Inverse Reinforcement Learning for Mean-Field Games

This paper proposes a kernel-based maximum causal entropy inverse reinforcement learning framework for infinite-horizon stationary mean-field games that models unknown rewards in a reproducing kernel Hilbert space to capture nonlinear structures, proves the algorithm's theoretical consistency via Fréchet differentiability, and demonstrates superior policy recovery performance over linear baselines in traffic routing scenarios while extending the approach to finite-horizon non-stationary settings.

The inverse initial data problem for anisotropic Navier-Stokes equations via Legendre time reduction method

This paper introduces a novel computational framework that utilizes Legendre time-dimensional reduction to transform the inverse initial-data problem for compressible anisotropic Navier-Stokes equations into a solvable system of elliptic equations, enabling the robust and accurate reconstruction of initial velocity fields from noisy boundary observations.

Lp\mathrm{L}^p-based Sobolev theory on closed manifolds of minimal regularity: Vector-valued problems

This paper establishes the well-posedness and Lp\mathrm{L}^p-based Sobolev regularity for vector-valued fluid dynamics PDEs, including Stokes and Navier–Stokes equations, on closed manifolds of minimal regularity by developing a parametrization-free variational approach that decouples velocity and pressure variables.

Benford behavior resulting from stick and box fragmentation processes

This paper investigates Benford's law in stick and box fragmentation models by reducing multi-proportion stick fragmentation to a single-proportion case using combinatorial identities, establishing necessary and sufficient conditions for strong Benford convergence based on irrationality exponents, and proving that high-dimensional box fragmentation satisfies strong Benford behavior under mild conditions.

Inertial accelerated primal-dual algorithms for non-smooth convex optimization problems with linear equality constraints

This paper proposes an inertial accelerated primal-dual algorithm derived from a time-scaled second-order differential system to solve non-smooth convex optimization problems with linear equality constraints, establishing fast convergence rates for the primal-dual gap, feasibility violation, and objective residual, and validating its performance through numerical experiments.
