## Material deformation tensor in time-reversal symmetry breaking turbulence

The Lagrangian evolution of material elements has been extensively studied in various works [1], [2] and [3]. These studies were connected with different problems: such as Lagrangian turbulence [5] or passive scalar decay [2]. One of the most important results of these studies is the proof of the intermittency in structure functions. This intermittency seems closely connected with the intermittency of the developed turbulence
