A Cayley-Hamilton trace identity for 2 x 2 matrices over Lie-solvable rings

Johan Meyer, Jeno Szigeti, Leon van Wyk

We exhibit a Cayley-Hamilton trace identity for $2 \times 2$ matrices with entries in a ring $R$ satisfying $[[x, y], [x, z]] = 0$ and 1/2 \in R$.

Cayley Hamilton theorem with sandwich coefficients for n $\times$ n matrices over a ring satisfying [x,y][u,v]=0

Jeno Szigeti

If A is an n \times n matrix over a ring R satisfying the polynomial identity [x,y][u,v]=0, then an invariant Cayley-Hamilton identity of the form ΣA^{i}c_{i,j}A^{j}=0 with c_{i,j}…

The zero-level centralizer in endomorphism algebras

Jenő Szigeti, Leon van Wyk

For an endomorphism f\inEnd{M) of a left R-module M we investigate the structure and the polynomial identities of the zero-level centralizer Cen_0(f) and the factor Cen(f)/Cen_0(f)…
