On Fractional Instanton Numbers in Six Dimensional Heterotic E_8 x E_8 Orbifolds
Jan O. Conrad
We show how the level matching condition in six dimensional, abelian and supersymmetric orbifolds of the E_8 x E_8 heterotic string can be given equivalently in terms of fractional…

On Fractional Instanton Numbers in Six Dimensional Heterotic E8 x E8 Orbifolds
Jan O. Conrad
We derive the precise relation between level matching condition and fractional instanton numbers in six dimensional, abelian and supersymmetric orbifolds of E8 x E8 heterotic strin…

Brane Tensions and Coupling Constants from within M-Theory
Jan O. Conrad
Reviewing the cancellation of local anomalies of M-theory on R^10 x S^1/Z_2 the Yang-Mills coupling constant on the boundaries is rederived. The result is lambda^2 = 2^(1/3) (2 pi)…
