1. A turbomachine comprising a rotor and a stator, the stator comprising a plurality of profiled structures, each profiled structure,
being elongated in a direction of elongation in which the profiled structure has a length exposed to an airflow, and
having a leading edge and/or a trailing edge, at least one of which is profiled and has, in said direction of elongation, serrations defined by a succession of peaks and troughs,
the serrations having a geometric pattern transformed, over at least a part of said length exposed to the airflow, by successive scaling, via multiplicative factors, in the direction of elongation and/or transverse to the direction of elongation,
wherein, defined with reference to a radial distribution of the integral scale of the turbulence, the geometric pattern evolves in a non-periodic manner:
in the direction of elongation, according to a linear, quadratic, hyperbolic, exponential or logarithmic law of evolution, and/or
transversely to the direction of elongation, according to a linear, quadratic, hyperbolic, exponential or logarithmic law of evolution.
