Abstract

Let Φ\Phi be a CC^*-subalgebra of L(R)L^\infty(\mathbb{R}) and SOX(R)SO_{X(\mathbb{R})}^\diamond be the Banach algebra of slowly oscillating Fourier multipliers on a Banach function space X(R)X(\mathbb{R}). We show that the intersection of the Calkin image of the algebra generated by the operators of multiplication aIaI by functions aΦa\in\Phi and the Calkin image of the algebra generated by the Fourier convolution operators W0(b)W^0(b) with symbols in SOX(R)SO_{X(\mathbb{R})}^\diamond coincides with the Calkin image of the algebra generated by the operators of multiplication by constants.
