Let p be an odd prime and q a power of p . We examine the deformation theory of reducible and indecomposable Galois representations ρ ̄ : G ℚ → GSp 2 n ( 𝔽 q ) that are unramified outside a finite set of primes S and whose image lies in a Borel subgroup. We show that under some additional hypotheses, such representations have geometric lifts to the Witt vectors W ( 𝔽 q ) . The main theorem of this paper is a higher-dimensional generalization of the result of [S. Hamblen and R. Ramakrishna, Deformations of certain reducible Galois II, Amer. J. Math . 130 (4) (2008) 913–944] [5].

某些可约伽罗瓦表示的变形 III
让p 是一个奇数素数并且q 一种力量p . 我们研究了可约和不可分解的伽罗瓦表示的变形理论ρ ̄ : G ℚ → GSP 2 n ( 𝔽 q ) 在有限素数集之外没有分支的小号 并且其图像位于 Borel 子群中。我们表明,在一些额外的假设下,这种表示对 Witt 向量有几何提升W ( 𝔽 q ) . 本文的主要定理是 [S. Hamblen and R. Ramakrishna, Deformations of certain reducible Galois II,阿米尔。J.数学 .130 (4) (2008) 913–944] [5]。
