Overview

Christophe Letellier is affiliated with the University of Rouen in France and is an active researcher primarily in the fields of Physics and Astronomy as well as Computer Science. Their work extensively covers subfields such as Statistical and Nonlinear Physics, Computer Networks and Communications, Mathematical Physics, Economics and Econometrics, and Cognitive Neuroscience.

The main topics addressed in their research include:

  • Chaos control and synchronization
  • Nonlinear Dynamics and Pattern Formation
  • Quantum chaos and dynamical systems
  • Mathematical Dynamics and Fractals
  • Complex Systems and Time Series Analysis
  • Neural dynamics and brain function
  • stochastic dynamics and bifurcation

Letellier's recent publications reflect a focus on nonlinear dynamics and chaos theory. Selected papers include:

  • "Optimal flatness placement of sensors and actuators for controlling chaotic systems," 2021, Chaos An Interdisciplinary Journal of Nonlinear Science
  • "Some elements for a history of the dynamical systems theory," 2021, Chaos An Interdisciplinary Journal of Nonlinear Science
  • "Templex: A bridge between homologies and templates for chaotic attractors," 2022, Chaos An Interdisciplinary Journal of Nonlinear Science
  • "Dynamical Taxonomy: Some Taxonomic Ranks to Systematically Classify Every Chaotic Attractor," 2022, International Journal of Bifurcation and Chaos
  • "Chaos: From theory to applications for the 80th birthday of Otto E. Rössler," 2021, Chaos An Interdisciplinary Journal of Nonlinear Science

The scholar frequently publishes in venues such as:

  • Chaos An Interdisciplinary Journal of Nonlinear Science
  • Physical Review E
  • arXiv (Cornell University)
  • Chaos Solitons & Fractals
  • Communications in Nonlinear Science and Numerical Simulation

Collaboration is evident in their frequent co-authors, including Otto E. Rössler, I. Sendiña-Nadal, Ludovico Minati, Jean-Pierre Barbot, and I. Leyva.

Christophe Letellier has contributed to book literature with a forthcoming publication titled Recollections from the Early Days of Chaos Theory to be published by World Scientific in 2025.
