Abstract:
We display some examples of modulation-invariant multi-linear operators
which present certain curvature features: they either carry (maximal)
oscillatory factors that are complex exponentials or they can be represented
as more classical operators along curves. This is joint work with Bernicot,
Lie, Vitturi, Bernicot, Lie and respectively with Oliveira.
