Abstract
Let R be a central simple algebra finite-dimensional over its center F of characteristic 0. We will show that every element of reduced trace 0 in R can be expressed as [a,[c,b]]+λ[c,[a,b]] for some a,b,câR where λâ 0,â1. In addition, let D be a division algebra satisfying the conditions above. We will also show that the set of values of any nonzero multilinear polynomial of degree at most three, with coefficients from the center F of D, evaluated on Mk(D), kâ¥2, contains all matrices of reduced trace 0.
