Abstract

A refinement of Gr\"{u}ss type inequality for the Bochner integral of vector-valued functions in real or complex Hilbert spaces is given. Related results are obtained. Application for finite Fourier transforms of vector-valued functions and some particular inequalities are provided.

Keywords: Gruss inequality, Bochner integral, Fourier transforms, Hilbert spaces
