We compute the kinematical dependence of the peak luminosity, the pulse width and the spectral lag of the peak luminosity on the viewing angle θ_V of a jet. For appropriate model parameters we obtain the peak luminosity-spectral lag relation similar to the observed one including GRB980425. A bright (dim) peak with short (long) spectral lag corresponds to a jet with small (large) viewing angle. This suggests that the viewing angle of the jet might cause various relations in GRBs such as the peak luminosity-variability relation and the luminosity-width relation. Our model also suggests that X-ray rich GRBs (or X-ray flushes or Fast X-ray transients) are typical GRBs observed from large 9V with large spectral lag and low variability.

Two unique works about BRST cohomology [2] [3] miraculously inspire me to rewrite [1]. In the old preprint [1] we were thrown into confusion of gauge dependence about the Schwinger model with strong coupling limit, though in a very intelligible work [4] the authors concluded that the correlation functions of physical operators are constant. To put it differently they do not depend on any local coordinates. It is the property of the topological field theory. From a mathmatical proof which is connected with the gauge invariance of the energy-momentum tensors, we know that the energy-momentum tensor of the Yang-Mills theory can be always redefined so as to be BRST invariant [3]. Hence the present author optimistically decide to expect that under any gauge fixing conditions the Schwinger model with strong coupling limit is a topological field theory since the energy-momentum tensors can be always improved as a BRST invariant one and since we have shown that the energy-momentum tensors under two kinds of gauges can be represented as a commutator [Q_<BRST>, X], namely δ_BX [I]. Here δ_B denotes the BRST transformation.

This is the English translation of "Metriques Kahleriennes et Fibres Holomorphes" written by E. Calabi. The systematic way to construct the kahler metrics on the holomorphic bundles over the compact kahler manifolds or on their open sets which satisfy the certain axioms are studied. The section 4 and the section 5 are devoted to Einstein-kahler metrics on the line bundles over Einstein-kahler manifolds and to hyperkahler metrics, respectively. Many explicit examples such as the complete Ricci-flat kahler metrics on the canonical bundles of Einstein-kahler manifolds and the hyperkahler metrics on the cotangent bundles of the Fubini-Study spaces are included.
