Given a locally analytic representation $V$ of $G$, we modify the Schneider-Stuhler complex (originally defined for smooth representations) so as to give an `analytic' variant ${\\mathcal S}^A_\\bullet(V)$. The representations in this complex are built out of spaces of analytic vectors $A_\\sigma(V)$ for compact open subgroups $U_\\sigma$, indexed by facets $\\sigma$ of the Bruhat-Tits building of $G$. These analytic representations (of compact open subgroups of $G$) are then resolved using the Chevalley-Eilenberg complex from the theory of Lie algebras. This gives rise to a resolution ${\\mathcal S}^{\\rm CE}_{q,\\bullet}(V) \\rightarrow {\\mathcal S}^A_q(V)$ for each representation ${\\mathcal S}^A_q(V)$ in the analytic Schneider-Stuhler complex. In a last step we show that the family of representations ${\\mathcal S}^{\\rm CE}_{q,j}(V)$ can be given the structure of a Wall complex. The associated total complex ${\\mathcal S}^{\\rm CE}_\\bullet(V)$ has then the same homology as that of ${\\mathcal S}^A_\\bullet(V)$. If the latter is a resolution of $V$, then one can use ${\\mathcal S}^{\\rm CE}_\\bullet(V)$ to find a complex which computes the extension group $\\underline{Ext}^n_G(V,W)$, provided $V$ and $W$ satisfy certain conditions which are satisfied when both are admissible locally analytic representations.", "revisions": [ { "version": "v1", "updated": "2024-09-08T12:47:31.000Z" } ], "analyses": { "subjects": [ "22E50", "20G05", "11F85" ], "keywords": [ "compact open subgroups", "analytic schneider-stuhler complex", "associated total complex", "study resolutions", "wall complex" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
