Line bundle on riemann surface
Nettet10. apr. 2024 · A minimal map on a Riemann surface is nowhere injective if and only if it factors through a holomorphic branched cover [5, Section 3], or the surface admits an anti-holomorphic involution that leaves the map invariant [13, Theorem 1.1]. Pseudoholomorphic maps from a surface to a symplectic manifold have the same … NettetThis article is published in Topology.The article was published on 1976-01-01 and is currently open access.

Let X be a compact Riemann surface and W a vector bundle of rank n on X. n By the degree of W [denoted by d(W) ] we mean the degree of the line bundle A W. Definition 1: A vector bundle W on X is said to be stable [resp. semistable] if for every proper subbundle V of W, we have (rank W) d(V) < (rank V). d(W) [resp. (rank W)d(V) …

Nettetof no importance at all. What has to be understood is holomorphic or meromorphic functions on Riemann surfaces. It turns out that it is not only about functions but about holomorphic sections of holomorphic line bundles over a Riemann surface. Here one of the most famous results is the Riemann–Roch theorem. It gives us NettetThe Riemann curvature tensor is also the commutator of the covariant derivative of an arbitrary covector with itself:;; =. This formula is often called the Ricci identity. This is the classical method used by Ricci and Levi-Civita to obtain an expression for the Riemann curvature tensor. This identity can be generalized to get the commutators for two …

Element H^1(X,g) is a Lie algebra-valued function on the inresection of two charts, so we can roughly speaking exponentiate it to get a Lie group-value function on the same charts intersection and multply that function on the transition function defining the …
