In this paper, we prove the generalized Hyers-Ulam stability of a general k-quadratic Euler-Lagrange functional equation:for any fixed positive integer in intuitionistic fuzzy normed spaces using a fixed point method.

The generalized Hamiltonian representation of systems gives structural advantages that can be used in many areas. Some of these are the design of nonlinear observer and model-based fault diagnosis. Many works have as start point the generalized Hamiltonia... see more

In this paper, we investigate the stability problem in the spirit of Hyers-Ulam, Rassias and Gavruta for the quadratic functional equation: f(2x + y) + f(2x - y) = 2f(x + y) + 2f(x - y) + 4f(x) - 2f(y) in 2-Banach spaces. These results extend the generali... see more


A GENERALIZATION OF D’ALEMBERT, JENSEN AND QUADRATIC FUNCTIONAL EQUATIONS ON SEMIGROUPS

We determine the solutions f : S ? H of the generalized Jensen’s functional equationf (x + y) + f (x + f(y)) = 2f (x),    x,y ? S,and the solutions f : S ? H of the generalized quadratic functional equationf (x + y) + f (x + f(y)) = 2f (x) ... see more

We determine the Solutions f : S ? H of the generalized Jensen’s functional equationf( x + s(y)) + f( x + t(y)) = 2f(x), x , y? Sand the solutions f : S ? H of the generalized quadratic functional equationf ( x + s(y)) + f (x + t(y)) = 2f (x) + 2f (y), &n... see more

The paper deals with the simulation of  dynamical models of  constrained multibody systems which can be formulated as a set of  Differential Algebraic Equations (DAEs). We consider the general dynamical model resulting from Euler-Lagrange f... see more
