Weak solutions for a second order impulsive boundary value problem

K Zhang, J Xu, D O'Regan - Filomat, 2017 - doiserbia.nb.rs
In this paper we use topological degree theory and critical point theory to investigate the
existence of weak solutions for the second order impulsive boundary value problem {-x''(t)-λx …

M Haddaoui, H Lebrimchi, N Tsouli - Bol. Soc. Paran. Mat, 2021 - academia.edu
Put vn= un/|| un||, thus (vn) is bounded, for a subsequence still denoted (vn), we can assume
that vn⇀ v weakly in X, by Sobelev injection theorems we have vn→ v strongly in Lp (Ω) and …
