Abstract

We investigate LpL^p estimates for the ˉ\bar{\partial}-problem on rational Hartogs triangles Hm/n={(z1,z2)C2:z1m<z2n<1}\mathbb{H}_{m/n} = \{ (z_1, z_2) \in \mathbb{C}^2 : |z_1|^m < |z_2|^n < 1 \}. For p(1,)p \in (1, \infty), we establish the existence of a solution operator that is bounded on Lp(Hm/n)L^p(\mathbb{H}_{m/n}). Our approach avoid the need for any {\it a priori} condition on the data. We also show that the canonical solution KHm/nK_{\mathbb{H}_{m/n}} is bounded on Lp(Hm/n)L^p(\mathbb{H}_{m/n}) for p(p0,p2)p \in (p_0, p_2), where p0=2m+2nm+n+1+min{m,n}p_0=\frac{2m+2n}{m+n+1+\min\{m, n\}} and p2=2m+2nm+n1p_2=\frac{2m+2n}{m+n-1}. For classical Hartogs triangle, H1\mathbb{H}_1, this establishes boundedness for p(1,4)p \in (1, 4).
