The Tb theorem, like its predecessor, the T1 Theorem,
is a an L^2 boundedness criterion, originally established by McIntosh
and Meyer, and by David, Journe and Semmes in the context of singular
integrals, but later extended by Semmes to the setting of “square
functions”. The latter arise in many applications in complex function
theory and in PDE, and may be viewed as singular integrals taking values
in a Hilbert space. The essential idea of Tb and T1 type theorems, is that
