Abstract

It was proved by Kadets that a weak$^{*}$-continuous function on $[0,1]$ taking values in the dual of a Banach space $X$ is Riemann-integrable precisely when $X$ is finite-dimensional. In this note, we prove a Fréchet-space analogue of this result by showing that the Riemann integrability holds exactly when the underlying Fréchet space is Montel.
