CatDat

category of Banach spaces with linear contractions

  • notation: Ban\mathbf{Ban}
  • objects: Banach spaces over C\mathbb{C}
  • morphisms: linear contractions, i.e. linear maps of norm 1\leq 1
  • nLab Link

The choice of morphisms is similar to that of Met\mathbf{Met} which yields the best categorical properties.
