Abstract:
Hilbert proved that invariant rings are finitely generated for linearly reductive groups acting rationally on a finite dimensional vector space. Popov gave an explicit upper bound for the smallest integer $d$ such that the invariants of degree $\leq d$ generate the invariant ring. This bound has factorial growth. In this paper we will give a bound which depends only polynomially on the input data.References
