The dynamics of a function family over quadratic extensions of finite fields

This paper provides a complete description of the functional graph of the function f(X)=(cXq+aX)(XqX)n1f(X)=(cX^q+aX)(X^{q}-X)^{n-1} over the finite field Fq2\mathbb{F}_{q^2} by determining its cycle lengths, counting cycles, and classifying the attached tree structures in terms of arithmetic invariants of Fq\mathbb{F}_q.

Large Deviations and the Peano Phenomenon in Stochastic Differential Equations with Homogeneous Drift

This paper investigates first- and second-order large deviations for stochastic differential equations with non-Lipschitz homogeneous drifts, demonstrating that the small-noise limit converges to the set of extreme deterministic solutions and that the second-order exponential behavior is governed by the ground state of an associated Schrödinger operator.
