  abstract     = {Introduction to topological spaces \# We want now to extend the idea of continuity presented in limits , which is a function f : E n → E n is continuous if given x then ∀ ε > 0 ∃ δ such that ∀ y : ∥ y − x ∥ \&\#x3C; δ ⟹ ∥ f ( y ) − f ( x )∥ \&\#x3C; ε . But we want to get rid of the i}
