Seems to be strange at all:
I get in a special case no result at all .. just stops without any output and you get different results .. maybe Maple is just to weak for my math equations.
I just wanted to derive the simple pauli matrices's.

Maybe i should look out for some other Algebra-systems
Are there any Tipps? (Hot Question in an Maple forum!!)

Thanks again
But now I am coming up with an strange thing.
solve({conjugate(f)-g, seq(i, i = (VectorCalculus[DotProduct])(A, A)-E), seq(j, j = (VectorCalculus[DotProduct])(B, B)-E), seq(i, i = (VectorCalculus[DotProduct])(A, B)+(VectorCalculus[DotProduct])(B, A))})
don't bring an answer
solve({conjugate(g)-f, seq(i, i = (VectorCalculus[DotProduct])(A, A)-E), seq(j, j = (VectorCalculus[DotProduct])(B, B)-E), seq(i, i = (VectorCalculus[DotProduct])(A, B)+(VectorCalculus[DotProduct])(B, A))})
brings a nice one
1st case:
"conjugate(f)-g"
2nd case:
"conjugate(g)-f"
is the only difference
In my mathematical understanding this should be the same, so it should bring up the same answer
Or is there an option that must be set to force the solve to bring up the answer, or so...???

Thanks again

"solve({seq(i,i=A.A-E)});"
seems to be the right way but my real case is more complicated.
Maybe you could also help me in this case
A := Matrix(2, 2, {(1, 1) = a, (1, 2) = b, (2, 1) = c, (2, 2) = d})
B := Matrix(2, 2, {(1, 1) = e, (1, 2) = f, (2, 1) = g, (2, 2) = h})
E := Matrix(2, 2, {(1, 1) = 1, (1, 2) = 0, (2, 2) = 1, (2, 1) = 0})
N := Matrix(2, 2, {(1, 1) = 0, (1, 2) = 0, (2, 1) = 0, (2, 2) = 0})
solve({A.A=E, B.B=E, A.B+B.A=N}) don't work.
I tryed to solve seqences of solutions, and seqences of seqences, but didn't come to a working point.
