For a commutative ring k, the homotopy category of commutative Hk-algebras (strictly unital E∞ ring spectra under the Eilenberg-Mac Lane spectrum Hk) is equivalent to the homotopy category of E∞ differential graded k-algebras. The functor from topology to algebra is a CW approximation and cellular chain functor; the inverse equivalence is constructed by Brown’s representability theorem.

Abstract We provide an abstract characterization for the Cuntz semigroup of unital commutative AI-algebras, as well a semigroups form $\operatorname {\mathrm {Lsc}} (X,\overline {\mathbb {N}})$ some $T_1$ -space X . In our investigations, we also uncover new properties that all AI-algebras satisfies.

We give a full description of the Poisson structures on finitary incidence algebra $FI(P,R)$ an arbitrary poset $P$ over commutative unital ring $R$.

When replacing the non-negative real numbers with their addition by a commutative quantale V, under a metric lens one may then view small V-categories as sets that come with a V-valued distance function. The ensuing category V-Cat is well known to be a concrete topological category that is symmetric monoidal closed. In this paper we show which concrete symmetric monoidalclosed topological categ...

We show that if T is an isometry (as metric spaces) from an open subgroup of the group of the invertible elements in a unital semisimple commutative Banach algebra onto an open subgroup of the group of the invertible elements in a unital Banach algebra, then T (1)T is an isometrical group isomorphism. In particular, T (1)T is extended to an isometrical real algebra isomorphism from A onto B.

The structure of arbitrary associative commutative unital artinian algebras is well-known: they are finite products of associative commutative unital local algebras [6, pg.351, Cor. 23.12]. In the semi-simple case, we have the Artin-Wedderburn Theorem which states that any semi-simple artinian algebra (which is assumed to be associative and unital but not necessarily commutative) is a direct pr...

For a commutative associate unital ring R the notion of an Rconvolution type is introduced and applied to R-algebras. Some examples are presented and relations to known concepts are discussed. Mathematics Subject Classification (2010): 16S99, 13F99, 13F20, 13F25

We show that the algebra A of a commutative unital spectral triple (A,H,D) satisfying several additional conditions, slightly stronger than those proposed by Connes, is the algebra of smooth functions on a compact spin manifold.
