17 p, 419.6 KB Tips of tongues in the double standard family / Banerjee, Kuntal (Presidency University (India)) ; Buff, Xavier (Centre National de la Recherche Scientifique. Université de Toulouse.

We answer a question raised by Misiurewicz and Rodrigues concerning the family of degree two circle maps F : R/Z → R/Z defined by F(x):= 2x + a + sin(2πx) with λ:= (a, b) ∈ R/Z × (0, 1). We prove that if F - id has a zero of multiplicity three in R/Z, then there is a system of local coordinates (α, β): W → R defined in a neighborhood W of λ, such that α(λ) = β(λ) = 0 and F - id has a multiple zero with μ ∈ W if and only if β(μ) = α(μ).

21 p, 1.6 MB Julia sets with a wandering branching point / Buff, Xavier (Université Paul Sabatier. Institut de Mathématiques de Toulouse (France)) ; Canela Sánchez, Jordi (Université Paris-Est Marne-La-Vallée. Laboratoire d'Analyse et de Mathématiques Apliquées (France)) ; Roesch, Pascale (Université Paul Sabatier. Institut de Mathématiques de Toulouse (France))
According to the Thurston No Wandering Triangle Theorem, a branching point in a locally connected quadratic Julia set is either preperiodic or precritical. Blokh and Oversteegen proved that this theorem does not hold for higher degree Julia sets: there exist cubic polynomials whose Julia set is a locally connected dendrite with a branching point which is neither preperiodic nor precritical.

15 p, 164.2 KB Virtually repelling fixed points / Buff, Xavier (Université Paul Sabatier)
In this article, we study the notion of virtually repelling fixed point. We first give a definition and an interpretation of it. We then prove that most proper holomorphic mappings f : U → V with U contained in V have at least one virtually repelling fixed point.
