Corrigendum: Similarity degree of Fourier algebras

TL;DR

This paper corrects two errors in a previous work on Fourier algebras, confirming the main theorem's validity and partially resolving an example issue, thereby strengthening the original results.

Contribution

It provides necessary corrections to prior results on Fourier algebras, ensuring the main theorem remains valid and clarifies an example that was previously flawed.

Findings

Main theorem remains valid after correction

Errors in an example are partially resolved

Strengthens the theoretical foundation of Fourier algebra analysis

Abstract

We address two errors made in our paper arXiv:1511.03423. The most significant error is in Theorem 1.1. We repair this error, and show that the main result, Theorem 2.5 of arXiv:1511.03423, is true. The second error is in one of our examples, Remark 2.4 (iv), and we partially resolve it.
