Abstract :
In this article, we introduce a new class of analytic functions of the unit disc D namely the Exponential Cauchy Transforms K(e) defined by
f(z)=int_{T} exp[K(xz)]d mu(x)
where K (z) = (1 - z)^(-1) is classical Cauchy kernel and mu(x) is a complex Borel measures and x belongs to the unit circle T . We use Laguerre polynomials to explore the coefficients
of the Taylor expansions of the kernel and Peron’s formula to study the asymptotic
behavior of the Taylor coefficients. Finally we investigate relationships between our new
class K_{e} , the classical Cauchy space K and the Hardy spaces H^(p).
