Some sufficient conditions on the existence and multiplicity of solutions for the damped vibration problems with impulsive effects
⎧ u''(t) + g(t)u'(t) + f(t,u(t)) = 0, a.e. t ∈ [0,T
⎨ u(0) = u(T) = 0
⎩ $Δu'(t_{j}) = u'(t⁺_{j} - u'(t¯_{j}) = I_{j}(u(t_{j}))$, j = 1,...,p,
are established, where $t₀ = 0 < t₁ < ⋯ < t_{p} < t_{p+1} = T$, g ∈ L¹(0,T;ℝ), f: [0,T] × ℝ → ℝ is continuous, and $I_{j}: ℝ → ℝ$, j = 1,...,p, are continuous. The solutions are sought by means of the Lax-Milgram theorem and some critical point theorems. Finally, two examples are presented to illustrate the effectiveness of our results.
