Abstract
For a Hausdorff space , we exhibit an unexpected connection between the sectional number of the Fadell-Neuwirth fibration , and the fixed point property (FPP) for self-maps on . Explicitly, we demonstrate that a space has the FPP if and only if 2 is the minimal cardinality of open covers of such that each admits a continuous local section for . This characterization connects a standard problem in fixed point theory to current research trends in topological robotics.
