Abstract: | ![]() A collection of proper maps into a locally compact Hausdorff space X fixes the topology of X if the only locally compact Hausdorff topology on X which makes each element of continuous and proper is the given topology. In I2=[-1, 1]×[-1, 1], neither the collection of analytic paths nor the collection of regular twice differentiable paths fixes the topology. However, in I2, both the collection of C∞ arcs and the collection of regular C1 arcs fix the topology. In , the collection of regular injective entire rays together with either the collection of C∞ arcs or the collection of regular C1 arcs fixes the topology. |
