More recently, in the case of holomorphic vector bundles over a compact K¨ahler manifold, the algebraic-geometric notion of stability in the sense of Mumford-Takemoto has been shown by Donaldson [43] and Uhlenbeck-Yau
Stability of Vector Bundles on Surfaces and Curves
WebJan 1, 1986 · Publisher Summary. This chapter focuses on two concepts of stability for vector bundles and sheaves. By replacing ℋ with a Kähler form Φ, the concept of ℋ-stability to that of Φ -stability for vector bundles over compact Kähler manifolds that may or may not be algebraic. The chapter proves the theorem above under this general … WebThe 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 … free people flat sandals
