Abstract: | We prove that for any finite dimensional representation V of a finite group G of order n the quotient variety G??(V) is projectively normal with respect to descent of 𝒪(1)?l where l = lcm{1,2,3,4,…,n}. We also prove that for the tautological representation V of the alternating group An the projective variety An??(V) is projectively normal with respect to the descent of the above line bundle. |
