Operator-Norm Transfer and Cohomological Rigidity for Quaternionic Quasi-Lie Structures with Application to Sliding Mode ${\hat{I}}^2$-Exponential Stability

Nassim Athmouni, Nejib Brahmia, Tarek Fajraoui +1

We develop operator-theoretic and cohomological tools for quaternionic quasi-Lie structures, with sliding mode control as a motivating application. Three main results are establish…
