editNormal Fan
editOn the page of Normal fan on Wikipedia as one of the properties of normal fans it is written: "If F is a face of P of dimension d, then its normal cone C_F has dimension n – d." For this page there is only one reference and I couldn't find anywhere on this reference such an statement. Is it possible to suggest a more precise reference for this property?Mathlover854 (talk) 12:24, 20 September 2021 (UTC)
