摘要：
We prove a formula expressing the K-theoretic log Gromov-Witten invariants of a product of log smooth varieties V x W in terms of the invariants of V and W. The proof requires introducing log virtual fundamental classes in K-theory and verifying their various functorial properties. We introduce a log version of K-theory and prove the formula there as well.
