On the global properties of Fourier multipliers in the nonharmonic analysis setting
Wagner Augusto Almeida de Moraes
In this paper, we investigate the global properties of Fourier multipliers in the setting of nonharmonic analysis of boundary value problems. We give necessary and sufficient condi…

Regularity of solutions to a Vekua-type equation on compact Lie groups
Wagner Augusto Almeida de Moraes
We present sufficient conditions to have global hypoellipticity for a class of Vekua-type operators defined on a compact Lie group. When the group has the property that every non-t…
