Quadratic Function with Fuzziness of a Fixed Point

The fuzzy logic fixed points assist in the examination of system stability in the control systems and clustering domain. They are used in fuzzy equations solving and optimization of fuzzy algorithms. The fixed point theory used in fuzzy systems guarantees convergence and stability as it provides an intermediate between uncertainty (fuzziness) and certain mathematical laws. Combining fuzzy logic with fixed-point theory is a strong mathematical basis of studying systems with uncertainty. Fuzzy fixed points are also useful in analyzing stability in control systems and clustering algorithms, solving fuzzy equations, and optimization of fuzzy algorithms. Fixed-point theory in fuzzy systems, by censoring the distance between uncertainty (fuzziness) and fixed mathematical laws, provides convergence and stability, and provides a more realistic model of the imperfect real world.

The study uses the analytical and numerical methodology in order to study the impact of fuzziness on fixed points in a systematic way. With the introduction of a fuzziness parameter (µ), and operated around a symmetric interval, a classical fixed-point will become a fuzzy mapping. Further breakdown into the functions of linear, quadratic, trigonometric and radical functions will show how fuzziness transforms a deterministic fixed point to a solution interval. The findings indicate that although linear systems have steady and equal interval shifts, nonlinear functions had more complicated and delicate behaviors, such as interval expansion and possible bifurcations. This interval representation of fixed points provides a more useful and more precise representation to use in applications in both control systems and economic modeling and dynamical systems in which parameters are inherently imprecise. The paper concludes by finding classical numerical methods to be still useful, but they need to be reinterpreted where convergence is to a region of solution instead of a point.
