Stability of Invariant Lagrangian Subspaces I,ons of the matrix or the operator, attracted much attention (see [BGK, GR, GLR1, AFS]). The main motivation to consider these problems comes from factorizations of matrix and operator functions, where invariant subspaces appear as the main tool in describing the factorizations (for this approach to factorization see, e.g., [BGK, GLR2]).作者: Demulcent 時(shí)間: 2025-3-25 15:20 作者: 引導(dǎo) 時(shí)間: 2025-3-25 17:16 作者: 可轉(zhuǎn)變 時(shí)間: 2025-3-25 20:13 作者: expunge 時(shí)間: 2025-3-26 01:04 作者: MILL 時(shí)間: 2025-3-26 05:45
