Throughout section 4.2, we should still have the condition that Failed to parse (Missing texvc executable; please see math/README to configure.): J
doesn't contain Failed to parse (Missing texvc executable; please see math/README to configure.): 1
. Right?
There also seems to be an issue with the basis for Failed to parse (Missing texvc executable; please see math/README to configure.): \Omega^{Spin}_*\otimes\mathbb{Z}_2 . The third dot point reads "Failed to parse (Missing texvc executable; please see math/README to configure.): M_J\times\omega_8^k
with Failed to parse (Missing texvc executable; please see math/README to configure.): k \geq 0
, Failed to parse (Missing texvc executable; please see math/README to configure.): n(J)
odd". But Failed to parse (Missing texvc executable; please see math/README to configure.): M_J is only defined for Failed to parse (Missing texvc executable; please see math/README to configure.): n(J) even.
I can think of two possibilities of what was meant:
1. "Failed to parse (Missing texvc executable; please see math/README to configure.): n(J)
odd" should be "Failed to parse (Missing texvc executable; please see math/README to configure.): n(J) even". If this was what was intended, then this is covered by the first dot point with Failed to parse (Missing texvc executable; please see math/README to configure.): i = 0 so the third dot point is unnecessary.
2. Failed to parse (Missing texvc executable; please see math/README to configure.): M_J
should be Failed to parse (Missing texvc executable; please see math/README to configure.): N_J
. If this is the case, then the fifth dot point is no longer needed (just take Failed to parse (Missing texvc executable; please see math/README to configure.): k = 0 ).
