Did you not have claimed the following?

Yes I did. But in context, that hardly seems like an extraordinary
claim; it's a quite ordinary claim.

For example, I have the following simple matrix

[snip remaining]

TENSORS ARE NOT MATRICES.

My tensors allow fractional indices.
A few years ago fractional exponents
was considered unusual, but today,
it's good stuff, like 4^(1/2) = 2.

Using these contravariant tensors,

X^u = x^(u+1)

solve X to x.

That should keep Gisse and the mammilian
off-spring engaged for a few generations.
