Abstract :
This work reports noise-induced effects on the instabilities appearing near the first threshold, i.e. near the transition from the homogeneous to the patterned state. This study also shows that some characteristics (such as the wave number) of the pattern appearing above threshold are anticipated below threshold by precursors.
