On nonlinear quasi-contractions

open access: yes, 2008
Lj. Ciric [2] first introduced the notion of quasi - contractions and proved the fixed point theorem for this class of mappings. Ciri'c's result was extended to nonlinear quasi - contractions by A. A. Ivanov [4]. In this paper we present new generalizations of Ivanov's fixed point theorem.

Adaptive Nonlinear Control With Contraction Metrics

IEEE Control Systems Letters, 2021
This letter derives direct adaptive control algorithms for nonlinear systems nominally contracting in closed-loop, but subject to structured parametric uncertainty. The approach is more general than methods based on feedback linearization or backstepping as it does not require invertibility or the system be in strict-feedback form. More broadly, it can

On random nonlinear contractions

Mathematical Systems Theory, 1977
A fixed point theorem for random nonlinear contraction mappings is proven. The random nonlinear contraction principle is then used to study the existence and uniqueness of solutions for a class of random nonlinear integral equations.
