Dear support:
On sagenb.org:
{{{id=4|
A = Matrix([[1,2,3],[3,2,1],[1,1,1]])
A.eigenvectors_left();A.eigenspaces_left()
///
[(5, [
(1, 1, 1)
], 1), (0, [
(1, 1, -4)
], 1), (-1, [
(1, -1/5, -7/5)
], 1)]
[
(5, Vector space of degree 3 and dimension 1 over Rational Field
User basis matrix:
[1 1 1]),
(0, Vector space of degree 3 and dimension 1 over Rational Field
User basis matrix:
[ 1 1 -4]),
(-1, Vector space of degree 3 and dimension 1 over Rational Field
User basis matrix:
[ 1 -1/5 -7/5])
]
}}}
But if I click "Typeset":
{{{id=4|
A = Matrix([[1,2,3],[3,2,1],[1,1,1]])
A.eigenvectors_left();A.eigenspaces_left()
///
<html><span class="math">\begin{array}{l}[\left(5,
\left[\left(1,1,1\right)\right],
1\right),\\
\left(0,
\left[\left(1,1,-4\right)\right],
1\right),\\
\left(-1,
\left[\left(1,-\frac{1}{5},-\frac{7}{5}\right)\right],
1\right)]\end{array}</span></html>
<html><span class="math">\begin{array}{l}[\left(5,
\mbox{\rm RowSpan}_{\mathbf{Q}}\left(\begin{array}{rrr}
1 & 1 & 1
\end{array}\right)\right),\\
\left(0,
\mbox{\rm RowSpan}_{\mathbf{Q}}\left(\begin{array}{rrr}
1 & 1 & -4
\end{array}\right)\right),\\
\left(-1,
\mbox{\rm RowSpan}_{\mathbf{Q}}\left(\begin{array}{rrr}
1 & -\frac{1}{5} & -\frac{7}{5}
\end{array}\right)\right)]\end{array}</span></html>
}}}
And the second thing does not render properly in Safari for me; I
actually see the \rm and it looks not so nice. Putting brackets {}
around this doesn't seem to help. Any ideas? Maybe the \mbox doesn't
like my TeX fonts? Anyway the \rm doesn't seem particularly helpful -
is it needed?
Thanks,
