Query: Weak BMO and Toeplitz operators on Bergman spaces   Inspired by our previous work on the boundedness of Toeplitz operators, we
introduce weak BMO and VMO type conditions, denoted by BWMO and VWMO,
respectively, for functions on the open unit disc of the complex plane. We show
that the average function of a function $f$ in BWMO is boundedly oscillating,
and the analogous result holds for $f$ in VWMO. The result is applied for
generalizations of known results on the essential spectra and norms of Toeplitz
operators. Finally, we provide examples of functions satisfying the VWMO
condition which are not in the classical VMO or even in BMO.
