Objective Eulerian Coherent Structures
Mattia Serra, George Haller
We define objective Eulerian Coherent Structures (OECSs) in two-dimensional, non-autonomous dynamical systems as instantaneously most influential material curves. Specifically, OEC…

Dynamic Rotation and Stretch Tensors from a Dynamic Polar Decomposition
George Haller
The local rigid-body component of continuum deformation is typically characterized by the rotation tensor, obtained from the polar decomposition of the deformation gradient. Beyond…
