    • Martínez, Salomé; Salazar, Dora (Cambridge Univ Press, 2020)
      In this paper, we are concerned with unbounded solutions of the singularly perturbed forced pendulum equation in the presence of friction, namely e(2)u(x)" e + sinue = e2a( t)ue + e2 beta(t)u e in (- L, L). Using a limiting ...
    • Cantrell, Robert Stephen; Cosner, Chris; Martínez, Salomé; Torres, Nicolás (Academic Press Inc., 2018)
      In this article we study the long term behavior of the competitive system {[Formula presented]=∇⋅[α(x)∇[Formula presented]]+u(m(x)−u−bv)inΩ,t>0,[Formula presented]=∇⋅[β(x)∇v]+v(m(x)−cu−v)inΩ,t>0,∇[Formula ...
