设为单位圆盘上的正则次调和权,设为与之相关的加权Bergman空间。本文考虑紧Hankel算子,其解析符号为共轭,作用于,给出了其迹的上下估计,其中,是凸函数。其次,我们给出了它们奇异值的渐近估计。我们也考虑了Toeplitz算子的类似问题。
Letbe a regular subharmonic weight on the unit disc and letbe the weighted Bergman space associated with. We consider compact Hankel operators, with conjugate analytic symbols, acting on. We give a lower and an upper estimates of the trace of, wherehis a convex function . Next, we give asymptotic estimates of their singular values. We also consider the similar problem for Toeplitz operators.
