Yukawa-type system
From DispersiveWiki
for d = 3. A represents the meson field, while u is the nucleon field.
Global well posedness in the energy class (H1,H1xL2) is in Bch1984, BlChd1978, FuTs1978, HaWl1987. Modified wave operators were constructed for large energy data at infinity in GiVl-p2.
With positive mass m=1, global well-posedness can be pushed to (Hs,HmxHm − 1) whenever 
and s + m > 3 / 2Pe-p2.
