Hello,

We have an abstract manifold M and a chart x.

A student (friend) is writing $\displaystyle det(\delta_1 x_p,..,\delta_n x_p)=... $.

whereas the det should be a determinant and $\displaystyle \delta_i x_p$ the basis vectors of T_p M induced by the chart.

I cann't see any sense in it. Maybe it is senseless. But maybe he uses some identifications (e.g. with some coefficients) or something like that.

What do you think?

Regards
