A Tutorial %A Roberto Barrio %A Andrey Shilnikov %A Leonid Shilnikov %J Physics %D 2012 %I arXiv %X A new computational technique based on the symbolic description utilizing kneading invariants is proposed and verified for explorations of dynamical and parametric chaos in a few exemplary systems with the Lorenz attractor. The technique allows for uncovering the stunning complexity and universality of bi-parametric structures and detect their organizing centers - codimension-two T-points and separating saddles in the kneading-based scans of the iconic Lorenz equation from hydrodynamics, a normal model from mathematics, and a laser model from nonlinear optics. %U http://arxiv.org/abs/1204.3278v1
