WebKolmogorov's normability criterion — A topological vector space is normable if and only if it is a T 1 space and admits a bounded convex neighbourhood of the origin. Because translation (that is, vector addition) by a constant preserves the convexity, boundedness, and openness of sets , the words "of the origin" can be replaced with "of some point" or even … http://users.ictp.it/~krs/pdf/1995_003.pdf
