For a locally compact group G and p ∈ (1, ∞), we study X(Lp(G)), the G-continuous operators on Lp(G), and the Banach algebra X(Lp(G))∗. We use a representation of the latter to show that, for infinite discrete groups G, the left topological centre condition on the convolution algebra N(ℓp(G)) of nuclear operators is equivalent to a commutation relation. Then, using an automatic normality result inspired by [16], we give a two-point left dtc set for N(ℓp(G)) in the case where G is abelian, and a two-point right dtc set for N(ℓp(G)) using results from [9].
