Web31 de mai. de 2011 · Let g be an analytic function on the unit disc and consider the integration operator of the form {T_g f (z) = \int_0^z fg'\,d\zeta}. We derive estimates for the essential and weak essential norms of T g on the spaces H p and BMOA. In particular, on H 1 and BMOA the operator T g is weakly compact if and only if it is compact. WebIn mathematics, in the area of functional analysis and operator theory, the Volterra operator, named after Vito Volterra, is a bounded linear operator on the space L 2 [0,1] of complex-valued square-integrable functions on the interval [0,1]. On the subspace C[0,1] of continuous functions it represents indefinite integration.It is the operator corresponding …
