\(L^p\)-\(L^q\) estimates for convolution operators with \(n\)-dimensional singular measures
Let \(d\sigma\) denote a compactly supported smooth density on the graph \(x_{n+1}= \sum^n_{j=1}| x_j|^{a_j}\), here \(a_j>0\). The authors prove nearly sharp \(L^p\)-\(L^q\) estimates for the convolution \(d\sigma* f\). For endpoint results see the authors' paper [Colloq. Math. 76, No. 1, 35-47 (1998; Zbl 0915.42009)].
