Abstract
In this paper, the norm of the Cauchy transform C is obtained on the space L 2(D, dμ), where dμ = ω(|z|) dA(z). Also, (for the case ω ≡ 1), the first regularized trace of the operator C* C on L 2(Ω) is obtained. The results are illustrated by examples, with different specific choices of the function ω and the domain Ω.
