The spectrum of Volterra operators on weighted spaces of entire functions

We investigate the spectrum of the Volterra operator $V_g$ with symbol an entire function $g$, when it acts on weighted Banach spaces $H_v^{\mathrm{\infty }}(\mathbb{C})$ of entire functions with sup-norms and when it acts on H"ormander algebras $A_p$ or $A_p^0$.
