概要
- 論文の詳細を見る
The topological conformal algebra for the models of bosonic string type is considered on an arbitrary higher-genus Riemann surface M. Associated with the U(1) anomaly the affine connection is automatically introduced into the algebra. The affine connection always appears in the form of covariant derivatives, so that it guarantees coordinate-independence of the algebra. Since our affine connection is meromorphic on M, the theorem that a globally defined holomorphic affine connection is admitted only on a torus is not applicable to our case. One may use it on general Riemann surfaces of genus g≥1 in the form of covariant derivatives.
