One-bubble nodal blow-up for asymptotically critical stationary Schrödinger-type equations
arxiv(2024)
摘要
We investigate in this work families (u_ϵ)_ϵ >0 of
sign-changing blowing-up solutions of asymptotically critical stationary
nonlinear Schrödinger equations of the following type:
Δ_g u_ϵ
+ h_ϵ u_ϵ = |u_ϵ|^p_ϵ-2 u_ϵ
in a
closed manifold (M,g), where h_ϵ converges to h in C^1(M).
Assuming that (u_ϵ)_ϵ >0 blows-up as a single
sign-changing bubble, we obtain necessary conditions for blow-up that
constrain the localisation of blow-up points and exhibit a strong interaction
between h, the geometry of (M,g) and the bubble itself. These conditions
are new and are a consequence of the sign-changing nature of u_ϵ.
