In this paper, we establish some results for a Volterra–Hammerstein integral equation with modified arguments: existence and uniqueness, inequalities, monotony Ulam-Hyers-Rassias stability. We emphasize that many problems from the domain of symmetry are modeled by differential equations those approached in stability point view. literature, Fredholm, Volterra Hammerstein integrals symmetric kern...
in this paper. (1) we determine the complex-valued solutions of the following variant of van vleck's functional equation $$int_{s}f(sigma(y)xt)dmu(t)-int_{s}f(xyt)dmu(t) = 2f(x)f(y), ;x,yin s,$$ where $s$ is a semigroup, $sigma$ is an involutive morphism of $s$, and $mu$ is a complex measure that is linear combinations of dirac measures $(delta_{z_{i}})_{iin i}$, such that for all $iin i$,...
Background and Objectives: Bioactive peptides have different health benefits and functional characteristics and are produced by enzymatic hydrolysis, microbial fermentation and chemical synthesis methods. The purpose of this study was to optimize the enzymatic hydrolysis conditions of fenugreek seed protein with alcalase and to evaluate the antioxidant properties of the resulting peptides. Mate...
Introduction In this study, we use a newly proposed method based on the software structure of the maple, called the Khaters method, and will be introducing exponential, hyperbolic, and trigonometric solutions for one of the Schrödinger equations, called the nonlinear Schrödinger equation with the dual power law nonlinearity. Given the widespread use of the Schrödinger equation in physics and e...
در ابتدا به طور مختصر ارتباط بین مسائل تغییراتی و معادلات دیفرانسیل را بیان می کنیم. همان طور که می دانیم هر معادله دیفرانسیل را می توان به صورت egin{equation} label{yek} a(u)= 0 end{equation} نوشت، که در آن $ a(u) $ یک عملگر دیفرانسیل معمولی یا جزئی خطی یا غیرخطی و $ u $ مجهول می باشد. برای حل این معادلات و به خصوص معادلات دیفرانسیل جزیی غیرخطی راه حل مشخصی وجود ندارد.حساب تغییر...
the aim of this paper is to show that under some mild conditions a functional equation of multiplicative (; )-derivation is superstable on standard operator algebras. furthermore, we prove that this generalized derivation can be a continuous and an inner (; )- derivation.
in this paper, we prove the generalized hyers-ulam(or hyers-ulam-rassias ) stability of the following composite functional equation f(f(x)-f(y))=f(x+y)+f(x-y)-f(x)-f(y) in various normed spaces.
the hydrogen abstraction reaction by oh radical from ch2brch2br (r1) and ch₃chbr2 (r2) is investigated theoretically by semi-classical transition state theory. the stationary points for both reactions are located by using ωb97x-d and kmlyp density functional methods along with cc-pvtz basis. single-point energy calculations are performed at the qcisd(t) and ccsd(t) levels of theory with differe...
