Difference of composition operators from the space of Cauchy integral transforms to Bloch-type spaces. Issue 2 (1st February 2017) - Sharma, Ajay K.
ABSTRACT: In this paper, we characterize boundedness and compactness of difference of composition operators from the space of Cauchy integral transforms to Bloch-type spaces. Our characterizations are free from pseudo-hyperbolic metric, which is a common feature of all the characterizations of difference of composition operators acting between different spaces of holomorphic functions. Exact value of operator norm of difference of composition operators acting between these spaces is also computed.
