Local zero estimates and effective division in rings of algebraic power series [PDF]

, 2015
We give a necessary condition for algebraicity of finite modules over the ring of formal power series. This condition is given in terms of local zero estimates.

Hypersurfaces of bounded Cohen--Macaulay type [PDF]

, 2003
Let R = k[[x_0,...,x_d]]/(f), where k is a field and f is a non-zero non-unit of the formal power series ring k[[x_0,...,x_d]]. We investigate the question of which rings of this form have bounded Cohen--Macaulay type, that is, have a bound on the ...

Operations on integral lifts of K(n)

, 2019
This very rough sketch is a sequel to arXiv:1808.08587; it presents evidence that operations on lifts of the functors K(n) to cohomology theories with values in modules over valuation rings of local number fields, indexed by Lubin-Tate groups of such ...

Formal Group Rings of Toric Varieties [PDF]

, 2015
In this paper we use formal group rings to construct an algebraic model of the $T$-equivariant oriented cohomology of smooth toric varieties. Then we compare our model with known results of equivariant cohomology of toric varieties to justify our ...

On spectral types of semialgebraic sets [PDF]

, 2013
In this work we prove that a semialgebraic set $M\subset{\mathbb R}^m$ is determined (up to a semialgebraic homeomorphism) by its ring ${\mathcal S}(M)$ of (continuous) semialgebraic functions while its ring ${\mathcal S}^*(M)$ of (continuous) bounded ...

Formal Fibers of Prime Ideals in Polynomial Rings [PDF]

, 2014
Let (R,m) be a Noetherian local domain of dimension n that is essentially finitely generated over a field and let R^ denote the m-adic completion of R.

The structure of the classifying ring of formal groups with complex multiplication

, 2015
If $A$ is a commutative ring, there exists a classifying ring $L^A$ of formal groups with complex multiplication by $A$, i.e., "formal $A$-modules." In this paper, the basic properties of the functor that sends $A$ to $L^A$ are developed and studied ...
