Abstract

The Lubin-Tate moduli space X0rigX_{0}^{\text{rig}} is a pp-adic analytic open unit polydisc which parametrizes deformations of a formal group H0H_{0} of finite height defined over an algebraically closed field of characteristic pp. It is known that the natural action of the automorphism group Aut(H0)\text{Aut}(H_{0}) on X0rigX^{\text{rig}}_{0} gives rise to locally analytic representations on the topological duals of the spaces H0(X0rig,(M0s)rig)H^{0}(X^{\text{rig}}_{0},(\mathcal{M}^{s}_{0})^{\mathrm{rig}}) of global sections of certain equivariant vector bundles (M0s)rig(\mathcal{M}^{s}_{0})^{\mathrm{rig}} over X0rigX^{\mathrm{rig}}_{0}. In this article, we show that this result holds in greater generality. On the one hand, we work in the setting of deformations of formal modules over the valuation ring of a finite extension of Qp\mathbb{Q}_{p}. On the other hand, we also treat the case of representations arising from the vector bundles (Mms)rig(\mathcal{M}^{s}_{m})^{\mathrm{rig}} over the deformation spaces XmrigX^{\mathrm{rig}}_{m} with Drinfeld level-mm-structures. Finally, we determine the space of locally finite vectors in H0(Xmrig,(Mms)rig)H^{0}(X^{\text{rig}}_{m},(\mathcal{M}^{s}_{m})^{\mathrm{rig}}). Essentially, all locally finite vectors arise from the global sections of invertible sheaves over the projective space via pullback along the Gross-Hopkins period map.
