Give a combinatorial interpretation of the formula:
{$ \mathrm{det}(e^A)=e^{\mathrm{tr}(A)} $}
- Give a combinatorial interpretation of {$ e^A$}.
- Relate {$\mathrm{tr}(A)$} to the weight lattice.
- Determinant gives the volume. Traces gives?
Note that this is central for the connection between the special linear Lie group (determinant of M is one) and the Lie algebra (trace of A is zero).
