摘要：

In this note we show that in dual N = 1 string vacua provided by the heterotic string on an elliptic Calabi-Yau together with a vector bundle respectively F-theory on Calabi-Yau fourfold the number of heterotic fivebranes necessary for anomaly cancellation matches the number of F-theory threebranes necessary for tadpole cancellation. This extends to the general case the work of Friedman, Morgan and Witten, who treated the case of embedding a heterotic E-8 x E-8 bundle, leaving no unbroken gauge group, where one has a smooth Weierstrass model on the F-theory side.
