Global attractivity of a higher order nonlinear difference equation with unimodal terms [PDF]
Opuscula Mathematica, 2023 In the present paper, we study the asymptotic behavior of the following higher order nonlinear difference equation with unimodal terms \[x(n+1)= ax(n)+ bx(n)g(x(n)) + cx(n-k)g(x(n-k)), \quad n=0, 1, \ldots,\] where \(a\), \(b\) and \(c\) are constants ...

Conflict between some higher-order curvature invariant terms
Nuclear Physics B, 2021 A viable quantum theory does not allow curvature invariant terms of different higher orders to be accommodated in the gravitational action. We show that there is indeed a conflict between the curvature squared and Gauss-Bonnet squared terms from the ...

Primary Students’ Math Literacy in terms of Higher Order Thinking Skill
Mimbar Ilmu, 2022 Primary students' math literacy is still inadequate. This is due to the limited number of problems based on math literacy, while studies analyzing math literacy require high-order thinking skills (HOTS).

Bouncing cosmology in modified gravity with higher-order curvature terms
Journal of High Energy Physics, 2023 A bouncing scenario of a flat homogeneous and isotropic universe is explored by using the reconstruction technique for the power-law parametrization of the Hubble parameter in a modified gravity theory with higher-order curvature and trace of the energy ...

Higher Order Expectations, Illiquidity, and Short-Term Trading [PDF]
SSRN Electronic Journal, 2011 When trading frequencies between liquidity traders and short term, heterogeneously informed investors differ, asset prices reflect Higher Order Expectations (HOEs) about both fundamentals and liquidity trading, and multiple, self-fulfilling equilibria arise.

Advanced Nonlinear Studies, 2023 We establish the Caccioppoli inequality, a reverse Hölder inequality in the spirit of the classic estimate of Meyers, and construct the fundamental solution for linear elliptic differential equations of order 2m2m with certain lower order terms.

Instabilities in metric-affine theories of gravity with higher order curvature terms
European Physical Journal C: Particles and Fields, 2020 We discuss the presence of ghostly instabilities for metric-affine theories constructed with higher order curvature terms. We mainly focus on theories containing only the Ricci tensor and show the crucial role played by the projective symmetry.

Williams Expansion Terms and their Importance for Accurate Stress Field Description in Specimens with a Crack [PDF]
Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, 2013 The paper deals with an analysis of the stress and displacement fields in various cracked specimens (loaded in mode I as well as in mode II). The main goal is to determine an accurate approximation of the near-crack-tip fields which can be subsequently
