The K-theory of the brane receives universal corrections coming from the Todd class of the target manifold. For that reason, the correct way to compute the charge of an embedded brane is Embed the brane. Compute the charge. In other words, computing the charge an performing an embedding are operations that do not commute, in a way measured by the ...

We take the frame where $p^\mu = (E,0,0,E)$. The components of $W_\mu$ are \begin{align} W_0 &= -\epsilon_{0312}P^3M^{12} = EJ_3,\;\; W_1 = -\epsilon_{1023}P^0M^{23} - \epsilon_{1302}P^3M^{02} = E(-J_1 + K_2),\\ W_2 &= -\epsilon_{2031}P^0M^{31} - \epsilon_{2301}P^3M^{01} = E(-J_2 - K_1),\;\; W_3 = -\epsilon_{3012}P^0M^{12} = -EJ_3,\\ W_\mu &= ...
