广义Robba环

Generalized Robba rings

Gergely Zábrádi

摘要:

证明了紧$p$ -adic李群的局部解析分布代数上的任意投射余容许模都是可积生成的.特别是,余容许模范畴没有足够的投射。在附录中构造了一致pro- $p$群的“广义Robba环”,它自然地包含局部解析分布代数作为子环。建设使用的准阿贝尔赋范代数,也有发展的广义微局部化理论。我们用自对偶局部凸拓扑扩充了分布代数上的拓扑,从而构造了广义Robba环.这是用来展示一些结果的余容许模。

英文摘要:

We prove that any projective coadmissible module over the locally analytic distribution algebra of a compact $p$-adic Lie group is finitely generated. In particular, the category of coadmissible modules does not have enough projectives. In the Appendix a "generalized Robba ring" for uniform pro-$p$ groups is constructed which naturally contains the locally analytic distribution algebra as a subring. The construction uses the theory of generalized microlocalization of quasi-abelian normed algebras that is also developed there. We equip this generalized Robba ring with a self-dual locally convex topology extending the topology on the distribution algebra. This is used to show some results on coadmissible modules.
