By Anwesh Ray

Let \(p\) be an odd prime and \(q\) a power of \(p\). We examine the deformation theory of reducible and indecomposable Galois representations \(\bar{\rho}:G_{\mathbb{Q}}\rightarrow \text{GSp}_{2n}(\mathbb{F}_q)\) 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,... Show more
