Stationary Subalgebras in General Position for Tensor Product

The paper studies stationary subalgebras in general position of compact linear groups. We prove that, except for several specific cases, a stationary subalgebra in general position of a tensor product of real or complex compact group representations acts as a scalar on all tensor factors but possibly one. In the real case, it means that this stationary subalgebra in general position is contained in one of the direct summand subalgebras. We used the following concepts to solve this problem: conventional linear algebra arguments; theory of Lie groups, Lie algebras and their representations; and methods similar to those of solving similar problems for complex reductive linear groups
