this is a bare list of references, to be !include
-ed into relevant entries (such as D-brane, Dirac charge quantization and D-brane charge quantization in K-theory).
In fact, the list is that which has been in each of these entries all along, and it has been a pain to synchronize the parallel lists. So this here now to ease the process.
I have made more explicit (here) the two observations that are the basis for the conjecture; and cross-linked more explicitly with Sen’s conjecture
after mentioning of Witten’s original argument about tachyon condensation, I added this comment (here):
The closest towards an actual check of this second argument about open superstring tachyon condensation (Witten 98, Section 3) seems to be
which concludes with:
It would also be interesting to see if these developments can shed light on the long-speculated relation between string field theory and the K-theoretic description of D-brane charge [75, 76, 77]. We leave these questions for future work.
and added this addendum (here):

which still lists (on p. 112) among open problems of string field theory:
“Are there topological invariants of the open string star algebra representing D-brane charges?”
added publication data for:
For when the editing functionality is back, to add some references on the suggestion to use some kind of “holomorphic K-theory” to see D-brane charges on CYs:
