Corrigenda : "stabilization in H∞R(D)" / Wick, Brett D. (Georgia Institute of Technology. School of Mathematics)
In this corrigenda we outline the necessary changes to the paper [3] so that the main result in that paper is made correct. The mistake the author made in the previous version was that the condition that f1 being positive on the zeros of f2 was not strong enough ∞ to guarantee the existence of the logarithm in HR (D).

Stabilization in Hr ∞ (D) / Wick, Brett D. (University of South Carolina. Department of Mathematics)
It is shown that for H∞/R(D)functions f1 and f2 with inf/z ∈D (│f1(z)│+ │f2(z) │≥ ᵟ > 0 and f1 being positive on the real zeros of f2, then there exists H∞/R (D) functions g2 and g1, g1 -1 with norm controlled by a constant depending only on ᵟ g1f1 + g2f2 = 1 ∀ z ∈ D. [...]

Closed ideals with countable hull in algebras of analytic functions smooth up to the boundary / Agrafeuil, Cyril ; Zarrabi, Mohamed (Université Bordeaux I. Laboratoire Bordelais d'Analyse et de Géométrie)
We denote by T the unit circle and by D the unit disc. Let B be a semi-simple unital commutative Banach algebra of functions holomorphic in D and continuous on D, endowed with the pointwise product. [...]
