Global hypoellipticity for a class of complex-valued evolution equations on compact Lie groups
Wagner A. A. de Moraes
We present necessary and sufficient conditions to have global hypoellipticity for a class of complex-valued coefficient first order evolution equations defined on $\mathbb{T}^1 \ti…
