From Partial and Horizontal Contraction to $k$-Contraction

Dynamical Systems 2022-08-31 v1

Abstract

A geometric generalization of contraction theory called~kk-contraction was recently developed using kk-compound matrices. In this note, we focus on the relations between kk-contraction and two other generalized contraction frameworks: partial contraction (also known as virtual contraction) and horizontal contraction. We show that in general these three notions of contraction are different. We here provide new sufficient conditions guaranteeing that partial contraction implies horizontal contraction, and that horizontal contraction implies kk-contraction. We use the Andronov-Hopf oscillator to demonstrate some of the theoretical results.
