What are D - branes (in a topological area concept)?

In the previous pair years, I've read several words concerning D - branes without sensation I have actually actually understood them. In wide terms, I assume I get what they have to do with: They are intended to act as environments for completions of open strings and also can be considered as submanifolds (of the target manifold in a sigma version), perhaps boosted with a vector package, or a sheaf of [somethings ], or possibly a few other sort of tag. (Please remedy me if I obtained that incorrect.)

In the hopes of tightening my understanding on the principle, below are several of the inquiries that have actually been irritating me throughout my analysis.

  1. What especially is the definition of a D - brane, claim in the context of a topological area concept? (Or what are one of the most encouraging provisionary interpretations?) What referrals are most obtainable to a mathematical target market?
  2. What image should I have in my head when a writer speaks about "the moduli space of D - branes"?
  3. What is the suggestion behind the "characteristics of D - branes" that scientists occasionally speak about? (Perhaps when I recognize far better just how to think of these gizmos, it will certainly be less complicated to visualize just how they need to transform with time.)
  4. What enters into validating (or at the very least asserting/conjecturing) that the components of twisted K - concept identify D - brane costs?

(I took into consideration placing this on MO, yet it really feels also standard about what TFT individuals speak about there for it to be ideal.)
