Templex: a bridge between homologies and templates for chaotic attractors
Gisela D. Charó, Christophe Letellier, Denisse Sciamarella
The theory of homologies introduces cell complexes to provide an algebraic description of spaces up to topological equivalence. Attractors in state space can be studied using Branc…
Observability analysis and observer design of networks of Rössler systems
Irene Sendiña-Nadal, Christophe Letellier
We address the problem of retrieving the full state of a network of Rössler systems from the knowledge of the actual state of a limited set of nodes. The selection of the nodes whe…
Dynamical Taxonomy: some taxonomic ranks to systematically classify every chaotic attractor
Christophe Letellier, Nataliya Stankevich, Otto E. Rössler
Characterizing accurately chaotic behaviors is not a trivial problem and must allow to determine the properties that two given chaotic invariant sets share or not. The underlying p…
Node differentiation dynamics along the route to synchronization in complex networks
Christophe Letellier, Irene Sendiña-Nadal, Ludovico Minati +1
Synchronization has been the subject of intense research during decades mainly focused on determining the structural and dynamical conditions driving a set of interacting units to…
Assessing observability of chaotic systems using Delay Differential Analysis
Christopher E. Gonzalez, Claudia Lainscsek, Terrence J. Sejnowski +1
Observability can determine which recorded variables of a given system are optimal for discriminating its different states. Quantifying observability requires knowledge of the equa…
Observability of dynamical networks from graphic and symbolic approaches
Irene Sendiña-Nadal, Christophe Letellier
A dynamical network, a graph whose nodes are dynamical systems, is usually characterized by a large dimensional space which is not always accesible due to the impossibility of meas…
