Constructing irreducible polynomials with prescribed level curves over finite fields

International Journal of Mathematics and Mathematical Sciences, 2001
We use Eisenstein's irreducibility criterion to prove that there exists an absolutely irreducible polynomial P(X,Y)∈GF(q)[X,Y] with coefficients in the finite field GF(q) with q elements, with prescribed level curves Xc:={(x,y)∈GF(q)2|P(x,y)=c}.

Active P-Y Curves for Rigid Walls Supporting Granular Soil

, 2023
Abstract In the performance-based design of structures with basement floors, there is interest in quantifying the relationship between the lateral earth pressure and the wall displacement using p-y curves. This paper focuses on studying the development of active earth pressure behind rigid walls in the context of p-y curves.

$L^p-L^q$ estimates for maximal operators associated to families of finite type curves

, 2020
We study the boundedness problem for maximal operators $\mathbb{M}$ associated to averages along families of finite type curves in the plane, defined by $$\mathbb{M}f(x) \, := \, \sup_{1 \leq t \leq 2} \left|\int_{\mathbb{C}} f(x-ty) \, \rho(y) \, d ...

Projective normality of Artin-Schreier curves

, 2013
In this paper we study the projective normality of certain Artin-Schreier curves $Y_f$ defined over a field $\F$ of characteristic $p$ by the equations $y^q+y=f(x)$, $q$ being a power of $p$ and $f\in \F[x]$ being a polynomial in $x$ of degree $m$, with $

Case study and practical analysis of lateral bearing characteristics of a single pile in Taihu soft soils using CPTU data

Yantu gongcheng xuebao, 2018
The muddy silty clay is rich in organic matter and widely distributed in Taihu soft soil foundation. It has a large water content and compressibility and is in a state of flow plasticity. All of these make it have bad engineering properties.
