Modular equations for Lubin-Tate formal groups at chromatic level 2
نویسندگان
چکیده
gives an equation for a curve that represents the moduli problem [Γ0(p)] for elliptic curves over a perfect field of characteristic p. This moduli problem associates to such an elliptic curve its finite flat subgroup schemes of rank p. A choice of such a subgroup scheme is equivalent to an isogeny from the elliptic curve with a prescribed kernel. The j-invariants of the source and target curves of this isogeny are parametrized by the coordinates j and j̃.

Semistable models for modular curves of arbitrary level
We produce an integral model for the modular curve X(Np) over the ring of integers of a sufficiently ramified extension of Zp whose special fiber is a semistable curve in the sense that its only singularities are normal crossings. This is done by constructing a semistable covering (in the sense of Coleman) of the supersingular part of X(Np), which is a union of copies of a Lubin-Tate curve. In ...
متن کاملThe Rigid Analytic Period Mapping, Lubin-tate Space, and Stable Homotopy Theory
The geometry of the Lubin-Tate space of deformations of a formal group is studied via an étale, rigid analytic map from the deformation space to projective space. This leads to a simple description of the equivariant canonical bundle of the deformation space which, in turn, yields a formula for the dualizing complex in stable homotopy theory. Introduction Ever since Quillen [22, 1 ] discovered ...
متن کاملLubin Tate Cohomology and Deformations of n-buds
We reprove Lazard’s result that every commutative n-bud is extendible to an n+ 1 bud, from an obstruction theoretic point of view. We locate the obstruction to extending an arbitrary n-bud in a certain cohomology group, and classify isomorphism classes of n-bud extensions for low degrees. 1 Lubin-Tate cohomology Definition 1. Let R be a commutative, unital ring and F a formal group law on R (as...
متن کاملLubin-Tate formal groups and module structure over Hopf orders
Over the last years Hopf orders have played an important role in the study of integral module structures arising in arithmetic geometry in various situations. We axiomatize these situations an discuss the properties of the (integral) Hopf algebra structures which are of interest in this general setting. In particular, we emphasize the role of resolvents for explicit computations. As an illustra...
متن کاملInteger Valued Polynomials and Lubin-tate Formal Groups
If R is an integral domain and K is its field of fractions, we let Int(R) stand for the subring of K[x] which maps R into itself. We show that if R is the ring of integers of a p-adic field, then Int(R) is generated, as an R-algebra, by the coefficients of the endomorphisms of any Lubin-Tate group attached to R.
