  We propose a formula for the exact central charge of a B-type D-brane that is
expected to hold in all regions of the Kahler moduli space of a Calabi-Yau. For
Landau-Ginzburg orbifolds we propose explicit expressions for the mathematical
objects that enter into the central charge formula. We show that our results
are consistent with results in FJRW theory and the hemisphere partition
function of the gauged linear sigma model.
