WebAug 3, 2012 · Hence 1897 is the year in which the representation theory of groups was born. Over the years 1897-1899 Frobenius published two papers on group representations, one on induced characters, and one on tensor product of characters. In 1898 he introduced the notion of induced representations and the Frobenius Reciprocity Theorem.
