%0 Journal Article %T On stability of diagonal actions and tensor invariants %A Artem Anisimov %J Mathematics %D 2010 %I arXiv %X For a connected simply connected semisimple algebraic group $G$ we prove existence of invariant tensors in tensor powers of rational $G$-modules and establish relations between existence of such invariant tensors and stability of diagonal actions of $G$ on affine algebraic varieties. %U http://arxiv.org/abs/1101.0053v2
