Let Ω be a bounded, smooth domain in ℝ 2. We consider the functional, in the supercritical Trudinger-Moser regime, i. e. for ∫ Ω{pipe}▼u{pipe} 2dx > 4π. More precisely, we are looking for critical points of I(u) in the class of functions u ε H 0 1(Ω) such that ∫ Ω{pipe}▼u{pipe} 2dx = 4π(1+α), for small α > 0. In particular, we prove the existence of 1-peak critical points of I(u) with ∫ Ω{pipe}▼u{pipe} 2dx = 4π(1+α) for any bounded domain Ω, 2-peak critical points with ∫ Ω{pipe}▼u{pipe} 2dx = 8π(1+α) for non-simply connected domains Ω, and k-peak critical points with ∫ Ω{pipe}▼u{pipe} 2dx = 4kπ(1+α) if Ω is an annulus.
