Abstract:
We consider convolution equations in the ultradistribution spaces $\mathcal {D}_{{L^q}}^{’({M_p})}$ and $\mathcal {D}_{{L^q}}^{’\{ {M_p}\} },\;q \in [1,\infty ]$, of Beurling and Roumieu type of ${L^q}$ growth. Our main aim is to find conditions for convolution operators to be hypoelliptic in $\mathcal {D}_{{L^\infty }}^{’({M_p})}$ and $\mathcal {D}_{{L^\infty }}^{’\{ {M_p}\} }$ respectively, in terms of their Fourier transforms.References
