El artículo tiene como propósito establecer un diálogo entre Watchmen, el cómic de Alan Moore y Dave Gibbons, su continuación televisiva, realizada bajo la dirección creativa Damon Lindelof. Este se establece sobre contenido político ambas obras, puntualmente en crítica al neoliberalismo régimen económico. Argumentamos que espacio temático narrativo tanto del serie es similar porque ambos const...

We give some necessary and sufficient conditions for the character of spaces to be preserved under closed maps. Introduction. Recall the following result due to K. Morita and S. Hanai [11] or A. H. Stone [14]: Let Y be the image of a metric space X under a closed map/. Then Y is first countable (or metrizable) if and only if every boundary df~x(y) of the point-inverse/"'^) is compact. E. Michae...

Theorem 2. Picard-Lindelof existence/uniqueness theorem Suppose f : (I × U) ⊆ (R × R) → R is continuous in (t, y) and uniformly Lipschitz in y. Then ∀(τ, ξ) ∈ (I × U), the ODE [ẏ = f(t, y) with y(τ) = ξ] has a unique solution on {t ∈ I : |t− τ | < α} for some α > 0. Depends on: Completeness of R, Gronwalls lemma (for uniqueness Proof idea: 5 steps: 1. Choose a, b s.t. {t : |t − τ | < a} ⊆ I and...
