Abstract
Let be a positive function defined near the origin such that . We consider the operator \begin{equation*} T_\theta f(x) = \lim_{\varepsilon\to 0^+} \int_\varepsilon^1 e^{i\gamma(t)}f(x-t) \frac{dt}{t^{\theta}\psi(t)^{1-\theta}}, \end{equation*} where is a real function with and . Assuming certain regularity and growth conditions on and , we show that is of weak type .
