Let μ be a positive Borel measure on the interval [ 0 , 1 ). The Hankel matrix H μ = ( μ n , k ) n , k 0 with entries μ n , k = μ n + k , where μ n = [ 0 , 1 ) t n d μ ( t ), formally induces the operator as follows:

D H μ ( f ) ( z ) = n = 0 ( k = 0 μ n , k a k ) ( n + 1 ) z n , z D ,

where f ( z ) = n = 0 a n z n is an analytic function in D . In this article, we characterize those positive Borel measures on [ 0 , 1 ) such that D H μ is bounded (resp., compact) from Bergman spaces A p into Hardy spaces H q , where 0 < p , q < .
