Hypersingular integral operators along surfaces

Hypersingular integral operators along surfaces

Abstract

In this paper, the author obtains the boundedness of certain singular integral operators along curves and surfaces with highly singular kernels. In the lower-dimensional case, the author studies the operator \[ Tf(u,v)= \text{p.v. }\int f(u-y, v-\gamma(y)) e^{i|y|^{-\beta}} y^{-1}|y|^{-\alpha} h(y) dy, \] where \(u,v,y\in \mathbb{R}\), \(h\) is a bounded, differentiable and even function, \(\gamma\) is a measurable even function such that \(|\gamma'(r)|\) is increasing on \((\text{supp }\gamma')\cap [0,\infty)\). Assume that either \(h\) is monotone or \(h'\in L^1(\mathbb{R})\) and that \(\gamma'\in L^1(\mathbb{R})\) or \(\gamma\in L^\infty(\mathbb{R})\) and \(\gamma(r)\) is monotone on \([0,\infty)\). The author proves that \(T\) is bounded on \(L^2(\mathbb{R}^2)\) provided \(0 0} r^{-1} \int_{|t|< r}|g(s-\gamma(t))|dt \] is bounded on \(L^p(\mathbb{R}^n)\) for \(1< p<\infty\). The author also extends the above result to the higher-dimensional case, where the singular integral operator \(Tf\) is defined as \[ Tf(x, x_n)= \text{p.v. }\int_{\mathbb{R}^{n-1}} f(x- y,x_n- \gamma(|y|)) e^{i|y|^{-\gamma}} h(y) \Omega(y)|y|^{-n+1-\alpha} dy, \] where \(x,y\in \mathbb{R}^{n-1}\), \(x_n\in \mathbb{R}\), \(\Omega\in L^q(S^{n-2})\) is homogeneous of degree zero and satisfies mean zero over the sphere \(S^{n-2}\). For more details and a weaker condition \(\Omega\in H^1\), the Hardy space, the reader can see another paper by the same author [``Singular integral operators along surfaces of revolution'', J. Math. Anal. Appl. 274, No. 2, 608-625 (2002; Zbl 1022.42008)].
