On Adic Genus and Lambda-rings
نویسنده
چکیده
Sufficient conditions on a space are given which guarantee that the K-theory ring is an invariant of the adic genus. An immediate consequence of this result about adic genus is that for any positive integer n, the power series ring Z[[x1, . . . , xn]] admits uncountably many pairwise non-isomorphic λ-ring structures.

Sufficient conditions on a space are given which guarantee that the K-theory ring and the ordinary cohomology ring with coefficients over a principal ideal domain are invariants of, respectively, the adic genus and the SNT set. An independent proof of Notbohm’s theorem on the classification of the adic genus ofBS by KO-theory λ-rings is given. An immediate consequence of these results about adi...
متن کاملModuli space of filtered lambda-ring structures over a filtered ring
Motivated by recent works on the genus of classifying spaces of compact Lie groups, here we study the set of filtered λ-ring structures over a filtered ring from a purely algebraic point of view. From a global perspective, we first show that this set has a canonical topology compatible with the filtration on the given filtered ring. For power series rings R[[x]], where R is between Z and Q, wit...

متن کاملRelaxed Hensel lifting of triangular sets
In this paper, we present a new lifting algorithm for triangular sets over general p-adic rings. Our contribution is to give, for any p-adic triangular set, a shifted algorithm of which the triangular set is a fixed point. Then we can apply the relaxed recursive p-adic framework and deduce a relaxed lifting algorithm for this triangular set. We compare our algorithm to the existing technique an...
متن کاملHigher dimensional 3-adic CM construction
We outline a method for the construction of hyperelliptic curves of genus 2 over small number fields whose Jacobian has complex multiplication and ordinary good reduction at the prime 3. We prove the existence of a quasi-quadratic time algorithm for canonically lifting in characteristic 3 based on equations defining a higher dimensional analogue of the classical modular curve X0(3). We give a d...
