Thread: Simple Minimal Polynomial Question

Supposed we have something like . How can we find the minimal polynomial of B?

I know if we had say A=J_6(0) and B=A^2. Then the min poly of B would be m(x)=x^3. Since B^3=(A^2)^3.

My concern with the first one is that we're not going to get a nice integer value. So would it be correct to say B^3=(A^6)^3*A^2... I'm a bit confused and could use some direction.

Hey Hal2001.

What do the J's refer to? Are they Bessel functions?

Oops. Sorry, they are Jordan blocks. Got it now, was just mixing up the notation, so what I originally wrote was off. Thanks again.
