Abstract
The goal of this work is to study the forward dynamics of positive solutions for the non-autonomous logistic equation ut -△u = λu - b(t)up, with p > 1, b(t) > 0, for all t ∈ ℝ limt_∞ b(t) -0. While the pullback asymptotic behaviour for this equation is now well understood, several different possibilities are realized in the forward asymptotic regime.
