## Abstract We consider twisted convolution operators with kernels having singularities on a sphere and having as Fourier transform the oscillatory symbol __m__~__Ξ±__~(|__ΞΎ__|) = |__ΞΎ__|^β__Ξ±__^__e__^__i__|__ΞΎ__|^, 0 β€ βοΈ__Ξ±__ < 2__n__. We give integral representations for such operators and, as a
