    Jordan Form

    Hi ALL !!! I must find the Jordan form of this operator: A(x_1, \ldots, x_6) = (2x_1+x_4+x_6,2x_2+x_5,2x_3,-x_1+3x_4+x_5+x_6,x_1+x_5-x_6,-x_1+x_4+x_5+4x_6) I found this matrix (is correct ?): \begin{pmatrix} 2 & 0 & 0 & 1 & 0 & 1 \\ 0 & 2 & 0 & 0 & 1 & 0 \\ 0 & 0 & 2 & 0 & 0 & 0 \\ -1 & 0 &...

    gauss vs gauss jordan

    Hi Guys, I have a simple and basic question.... I know what Gauss elimination is, and what we use it for, and also knows what Gauss Jordan is...what I wanted to know, is when do I use each one ? I mean, in order to solve a system of equations, Gauss is enough, so why do I need Gauss Jordan...

    Derivation and Jordan derivation

    Let R be ring, and d:R\toR is aditif mapping then d is called derivation if d(ab)=d(a)b+ad(b) \forall a,b\in R d is called Jordan derivation if d(a^2)=d(a)a+ad(a)\forall a\in R Obviously any derivation is Jordan derivation. But the converse is not true. (is there any example to show this...
