Resum

A study of non axisymmetric oscillations of differentially rotating 
neutron stars in the perturbative framework of General Relativity 
will be presented. Differential rotation plays an important role in 
nascent neutron stars, and recent numerical studies have shown that 
it can be responsible for an instability at low values of the ratio 
T/W. We study the oscillation spectrum of those stars and we 
investigate the possible effect of the existence of the corrotation 
band to the low T/W instability.
