It is proved that the restriction of any supercharacter of a finite group of triangular type to its subgroup is a sum of supercharacters with nonnegative integer coefficients. We define a superinduction and prove the analogue of Frobenius's reciprocity formula for supercharacters. Bibliography: 21 titles.
Keywords: supercharacter theory, triangular group, induced character, Frobenius reciprocity.
