Invariants of Formal Group Law Actions

0. Introduction. In this note, k denotes a field of characteristic p > 0, and the letters T, X and Y are formal indeterminants. Let F: k[[T]] —• /c[[X,Y]] be a (fixed) one-dimensional formal group law [Dieudonné, Hazewinkel, Lazard, Lubin] of height h > 0. Let V denote a k[[T]] module of finite length. Suppose Ann(V) = (T). Let q = p denote the least power of p such that n < q. It follows that ...

Separating Invariants for Arbitrary Linear Actions of the Additive Group

We consider an arbitrary representation of the additive group Ga over a field of characteristic zero and give an explicit description of a finite separating set in the corresponding ring of invariants.

Novikov-Shubin invariants for arbitrary group actions and their positivity

We extend the notion of Novikov-Shubin invariant for free Γ-CW complexes of finite type to spaces with arbitrary Γ-actions and prove some statements about their positivity. In particular we apply this to classifying spaces of discrete groups.

Bordism, and Free Group Actions

In this paper we give characteristic class formulae for all semicharacteristic classes of all compact, closed manifolds with finite fundamental groups. These invariants are identified with elements in certain odd L-groups, and exactly which elements occur is specified. An appendix calculates the cohomology of the model groups needed. A second appendix determines the structure of the L-groups ne...
