Nilpotent linear transformations and the solvability of power-associative nilalgebras

AbstractWe prove some results about nilpotent linear transformations. As an application we solve some cases of Albert’s problem on the solvability of nilalgebras. More precisely, we prove the following results: commutative power-associative nilalgebras of dimension n and nilindex n−1 or n−2 are solvable; commutative power-associative nilalgebras of dimension 7 are solvable
