• TITLE: Traversable Wormholes and the Brouwer Fixed-Point Theorem

  AUTHORS: Peter K. F. Kuhfittig

  KEYWORDS: Traversable Wormholes, Brouwer Fixed-Point Theorem

  JOURNAL NAME: Journal of Applied Mathematics and Physics, Vol.8 No.7, July 9, 2020

  ABSTRACT: The Brouwer fixed-point theorem in topology states that for any continuous mapping f on a compact convex set into itself admits a fixed point, i.e., a point x0 such that f(x0) = x0. Under suitable conditions, this fixed point corresponds to the throat of a traversable wormhole, i.e., b(r0) = r0 for the shape function b = b(r). The possible existence of wormholes can therefore be deduced from purely mathematical considerations without going beyond the existing physical requirements.
