On extension of solutions of a simultaneous system of iterative functional equations [PDF]

open access: yesOpuscula Mathematica, 2009
Some sufficient conditions which allow to extend every local solution of a simultaneous system of equations in a single variable of the form \[ \varphi(x) = h (x, \varphi[f_1(x)],\ldots,\varphi[f_m(x)]),\] \[\varphi(x) = H (x, \varphi[F_1(x)],\ldots ...

On the Nonlinear Vibrations and Stability Analysis of a Plate-Cavity System With a Nonlinear Restoring Force

open access: yesIEEE Access, 2021
This paper studies a nonlinear oscillation of a plate cavity system analytically. The system's nonlinear differential equations are described by a three-degree-of-freedom (3DOF) and subjected to parametric excitation forces.

Simultaneous equations [Maths problem]

open access: yes, 2023
When using the elimination method to solve simultaneous equations, students are often unsure whether to add or subtract. In this lesson, students explore what happens when they add and subtract pairs of simultaneous equations.

Note on simultaneous solutions of a system of Schröder's equations [PDF]

open access: yes, 1995
summary:We investigate simultaneous solutions of a system of Schroder's functional equations. Under certain assumptions these solutions are used in transformations of functional-differential equations the initial set of which consists of the initial ...
