| Abstract: | A block codeC Fn is calledmetrically rigid, if every isometry : C Fn with respect to theHamming metric is extendable to an isometry of the whole spaceFn. The metrical rigidity of some classes of codes is discussed.Dedicated to Helmut Karzel on the occasion of his 70th birthdayResearch supported by the Russian Foundation of Fundamental Research (Grant no. 97-01-01104)Research supported by the Russian Foundation of Fundamental Research (Grants no. 96-01-01800, 97-01-01075) |
