Multiplicative Operations in Bp*bp
where S is the Landweber-Novikov algebra. S has the added advantage of being a cocommutative Hopf algebra over Z. This paper does not remove this difficulty, but we will show that the monoid of multiplicative operations in BP*BP, (i.e. those operations which induce ring endomorphisms on BP*X for any space X)9 which we will denote by Γ{BP), has a submonoid analogous to the monoid of multiplicati...
متن کاملBP Operations and Morava's Extraordinary K-Theories
In a series of papers [17-19] Morava uses an infinite sequence of extraordinary K-theories to give an elegant structure theorem for the complex cobordism of a finite complex. Much of Morava's theory is embedded in a rather sophisticated algebraic setting. In our attempt to understand his work, we have found more conventional algebraic topological proofs of many of his results. Also, our approac...
متن کاملBinary operations and groups
Example 1.3. The examples are almost too numerous to mention. For example, using +, we have (N,+), (Z,+), (Q,+), (R,+), (C,+), as well as vector space and matrix examples such as (Rn,+) or (Mn,m(R),+). Using subtraction, we have (Z,−), (Q,−), (R,−), (C,−), (Rn,−), (Mn,m(R),−), but not (N,−). For multiplication, we have (N, ·), (Z, ·), (Q, ·), (R, ·), (C, ·). If we define Q∗ = {a ∈ Q : a 6= 0}, ...
متن کاملMonotone Operations and Monotone Groups∗
We survey an algebraic approach to proving impossibility results in distributed computing. The approach is emerging around monotone groups, a new class of algebraic groups we define here as a tight suit to monotone Read&Modify&Write (or RMW) operations in a distributed system. The yields of this approach have been the first impossibility results for implementations of monotone RMW operations th...
متن کاملFormal Operations for Ontology Evolution
Ontologies became more and more important for industrial usage one can see in projects like KAON [7] and KnowWork [15]. In this context ontologies will be continuously redesigned because of new market situations, restructuring of companies or because of increasing knowledge. Ontologies are used to represent the knowledge within these systems. For supporting the evolution of ontologies it is imp...
