Summary: Abstract
For 0 < 1/2 we characterize Carleson measures µ for the analytic
Besov-Sobolev spaces B
2 on the unit ball Bn in Cn
by the discrete tree
condition

µ ()

CI
µ () < , Tn,
on the associated Bergman tree Tn. Combined with recent results about
interpolating sequences this leads, for this range of , to a characteriza-
tion of universal interpolating sequences for B
2 and also for its multiplier
algebra.
