Description:
We study Kuzmin’s conjecture on the index of
nilpotency for the variety Nil5 of associative nil-algebras of de-
gree 5. Due to Vaughan-Lee the problem is reduced to that
for k-generator Nil5-superalgebras, where k ≤ 5. We confirm
Kuzmin’s conjecture for 2-generator superalgebras proving that
they are nilpotent of degree 15.
