James Maps and £ „ Ring Spaces
We parametrize by operad actions the multiplicative analysis of the total James map given by Caruso and ourselves. The target of the total James map J=2jqC(R",X)-^\[QDq(R",X) <7>0 is an En ring space and j is a S„-map, where 6„ is the little n-cubes operad. This implies thaty has an n-fold delooping with domain 2"X It also implies an algorithm for the calculation of j and thus of each (jq) on m...

متن کاملWhat Precisely Are E ∞ Ring Spaces and E ∞ Ring Spectra?
E∞ ring spectra were defined in 1972, but the term has since acquired several alternative meanings. The same is true of several related terms. The new formulations are not always known to be equivalent to the old ones and even when they are, the notion of " equivalence " needs discussion: Quillen equivalent categories can be quite seriously inequivalent. Part of the confusion stems from a gap i...
متن کاملThe Construction of E ∞ Ring Spaces From
The construction of E∞ ring spaces and thus E∞ ring spectra from bipermutative categories gives the most highly structured way of obtaining the K-theory commutative ring spectra. The original construction dates from around 1980 and has never been superseded, but the original details are difficult, obscure, and slightly wrong. We rework the construction in a much more elementary fashion.
متن کاملStability and hyperstability of orthogonally ring $*$-$n$-derivations and orthogonally ring $*$-$n$-homomorphisms on $C^*$-algebras
In this paper, we investigate the generalized Hyers-Ulam-Rassias and the Isac and Rassias-type stability of the conditional of orthogonally ring $*$-$n$-derivation and orthogonally ring $*$-$n$-homomorphism on $C^*$-algebras. As a consequence of this, we prove the hyperstability of orthogonally ring $*$-$n$-derivation and orthogonally ring $*$-$n$-homomorphism on $C^*$-algebras.
