Summary:  It has recently been established that if V is the classical Volterra (indefinite integration) operator acting on the Hilbert space L2([0,1]), then the operator and Hilbert-Schmidt norms of Vn are both asymptotically\break 1/(2n!). We extend this in two ways: firstly, we give a generalisation which applies to Volterra convolution operators with kernels satisfying a mild\break smoothness condition, and secondly we show that in the constant-kernel case the same asymptotic behaviour is shared by the trace norm, and hence by a wide class of operator norms.
