Abstract
We define and investigate the conjugate operator for Fourier–Bessel expansions. Weighted norm and weak type $(1,1)$ inequalities are proved for this operator by using a local version of the Calderón–Zygmund theory, with weights in most cases more general than $A_p$ weights. Also results on Poisson and conjugate Poisson integrals are furnished for the expansions considered. Finally, an alternative conjugate operator is discussed.
