Abstract
Let Ω be an irreducible bounded symmetric domain of genusp, h(x, y) its Jordan triple determinant, andA 2ν (Ω) the standard weighted Bergman space of holomorphic functions on Ω square-integrable with respect to the measureh(z, z) ν−p dz. Extending the recent result of Axler and Zheng for Ω=D, ν=p=2 (the unweighted Bergman space on the unit disc), we show that ifS is a finite sum of finite products of Toeplitz operators onA 2ν (Ω) and ν is sufficiently large, thenS is compact if and only if the Berezin transform\(\bar S\) ofS tends to zero asz approaches ∂Ω. An analogous assertion for the Fock space is also obtained.
