Multiplicative 2-cocycles at the prime 2
Using a previous classification result on symmetric additive 2-cocycles, we collect a variety of facts about the Lubin–Tate cohomology of certain formal groups to produce a presentation of the 2-primary component of the scheme of symmetric multiplicative 2-cocycles. This scheme classifies certain kinds of highly symmetric multiextensions, generalizing those studied by Mumford or Breen. A low-or...
متن کاملOn strongly 2-multiplicative graphs
In this paper we obtain an upper bound and also a lower bound for maximum edges of strongly 2 multiplicative graphs of order n. Also we prove that triangular ladder the graph obtained by duplication of an arbitrary edge by a new vertex in path and the graphobtained by duplicating all vertices by new edges in a path and some other graphs are strongly 2 multiplicative
متن کاملSome root invariants at the prime 2
The first part of this paper consists of lecture notes which summarize the machinery of filtered root invariants. A conceptual notion of “homotopy Greek letter element” is also introduced, and evidence is presented that it may be related to the root invariant. In the second part we compute some low dimensional root invariants of v1 -periodic elements at the prime 2. AMS Classification numbers P...
متن کامل2-absorbing $I$-prime and 2-absorbing $I$-second submodules
Let $R$ be a commutative ring and let $I$ be an ideal of $R$. In this paper, we will introduce the notions of 2-absorbing $I$-prime and 2-absorbing $I$-second submodules of an $R$-module $M$ as a generalization of 2-absorbing and strongly 2-absorbing second submodules of $M$ and explore some basic properties of these classes of modules.
متن کاملAnalytic multiplicative cocycles over holomorphic dynamical systems
We prove some properties of analytic multiplicative and sub-multiplicative cocycles. The results allow to construct natural invariant analytic sets associated to complex dynamical systems. AMS classification: 37F, 32H Key-words: multiplicative cocycle, sub-multiplicative cocycle, exceptional set
