Abstract
We prove weak (2, 2) bounds for maximally modulated anisotropically homogeneous smooth multipliers on \(\mathbb {R}^n\). These can be understood as generalizing the classical one-dimensional Carleson operator. For the proof we extend the time-frequency method by Lacey and Thiele to the anisotropic setting. We also discuss a related open problem concerning Carleson operators along monomial curves.

Notes
We can think of all the \(\mathcal {P}_\ell \) as being initialized by the empty set.
