Corrigendum

We correct Proposition 4.21 in Roch et al., “A Sequence Algebra of Finite Sections Convolution and Multiplication” 2 S. Roch , P. A. Santos , and B. Silbermann ( 2010 ). A sequence algebra of finite sections, convolution and multiplication operators on L ^p (?) . Numer. Funct. Anal.

The correction amounts to the observation that the spectrum of X is a single circular arc, not a lens.
