On Higher Order Drift and Diffusion Estimates for Stochastic SINDy

Mathias Wanner, Igor Mezić

The Sparse Identification of Nonlinear Dynamics (SINDy) algorithm can be applied to stochastic differential equations to estimate the drift and the diffusion function using data fr…

Explicit bounds for small prime nonresidues

Shilin Ma, Kevin J. McGown, Devon Rhodes +1

Let $χ$ be a Dirichlet character modulo a prime~ $p$ . We give explicit upper bounds on $q_{1} < q_{2} < \dots < q_{n}$ , the $n$ smallest prime nonresidues of $χ$ . More precisely, given $n_{0}$ an…

On the number of primes for which a polynomial is Eisenstein

Shilin Ma, Kevin McGown, Devon Rhodes +1

Previously Heyman and Shparlinski gave an asymptotic formula with error term for the number of Eisenstein polynomials of fixed degree and bounded height. Let $ψ (f)$ denote the numb…
