Asymptotic Behavior of Almost Quartic ⁎-Derivations on Banach ⁎-Algebras
Journal of Function Spaces, 2019 The purpose of this paper is to obtain the stability theorems of quartic ⁎-derivations associated with the quartic functional equation f(3x-y)+f(x+y)+6f(x-y)=4f(2x-y)+4f(y)+24f(x) on Banach ⁎-algebras.

Solution and Stability of a General Mixed Type Cubic and Quartic Functional Equation
Journal of Function Spaces and Applications, 2013 We consider the following mixed type cubic and quartic functional equation = where is a fixed integer. We establish the general solution of the functional equation when the integer , and then, by using the fixed point alternative, we investigate the ...

Minimum free-energy path of homogenous nucleation from the phase-field equation
, 2009 The minimum free-energy path (MFEP) is the most probable route of the nucleation process on the multidimensional free-energy surface. In this study, the phase-field equation is used as a mathematical tool to deduce the minimum free-energy path (MFEP) of ...

Nearly General Septic Functional Equation
Journal of Function Spaces, 2021 If a mapping can be expressed by sum of a septic mapping, a sextic mapping, a quintic mapping, a quartic mapping, a cubic mapping, a quadratic mapping, an additive mapping, and a constant mapping, we say that it is a general septic mapping.

The Cayley-Oguiso automorphism of positive entropy on a K3 surface
, 2012 Recently Oguiso showed the existence of K3 surfaces that admit a fixed point free automorphism of positive entropy. The K3 surfaces used by Oguiso have a particular rank two Picard lattice.

Quantization of chiral antisymmetric tensor fields
, 2005 Chiral antisymmetric tensor fields can have chiral couplings to quarks and leptons. Their kinetic terms do not mix different representations of the Lorentz symmetry and a local mass term is forbidden by symmetry.

Compact support probability distributions in random matrix theory [PDF]
, 1998 We consider a generalization of the fixed and bounded trace ensembles introduced by Bronk and Rosenzweig up to an arbitrary polynomial potential. In the large-N limit we prove that the two are equivalent and that their eigenvalue distribution coincides ...

American Journal of Agricultural Economics, EarlyView.Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Stability of Cubic and Quartic Functional Equations in Non-Archimedean Spaces [PDF]
Acta Applicandae Mathematicae, 2009 We prove generalized Hyres-Ulam-Rassias stability of the cubic functional equation $f(kx+y)+f(kx-y)=k[f(x+y)+f(x-y)]+2(k^3-k)f(x)$ for all $k\in \Bbb N$ and the quartic functional equation $f(kx+y)+f(kx-y)=k^2[f(x+y)+f(x-y)]+2k^2(k^2-1)f(x)-2(k^2-1)f(y)$ for all $k\in \Bbb N$ in non-Archimedean normed spaces.
