چکیده
Suppose B is an ultraproduct of finite dimensional C∗-algebras. We consider mapping and injectability properties for separable C∗algebras into B. In the case of approximately finite C∗-algebras, we obtain a classification of these mappings up to inner conjugacy. Using a Theorem of Voiculescu, we show that for nuclear C ∗-algebras injectability into an ultraproduct of finite dimensional C ∗-algebras is equivalent to quasidiagonality.

Nonstandard hulls of locally exponential Lie algebras
We show how to construct the nonstandard hull of certain infinite-dimensional Lie algebras in order to generalize a theorem of Pestov on the enlargeability of Banach-Lie algebras. In the process, we consider a nonstandard smoothness condition on functions between locally convex spaces to ensure that the induced function between the nonstandard hulls is smooth. We also discuss some conditions on...
متن کاملNonstandard methods in many-valued logics
Since MV-algebras include, in an essential way, infinitisimals it was felt that a systematic study of relationships of nonstandard methods and MV-algebras was needed. In this paper we try to introduce some basic frameworks to study MV-algebras from a nonstandard point of view. Also one can see that for a complete study of MV-algebras many external objects need to be treated differently.
متن کاملJu l 2 00 5 Derived Equivalence Classification of Nonstandard Selfinjective Algebras of Domestic Type
We give a complete derived equivalence classification of all nonstandard representation-infinite domestic selfinjective algebras over an algebraically closed field. As a consequence, a complete stable equivalence classification of these algebras is obtained.

A Riemannian Einstein solvmanifold is called standard, if the orthogonal complement to the nilradical of its Lie algebra is abelian. No examples of nonstandard solvmanifolds are known. We show that the standardness of an Einstein metric solvable Lie algebra is completely detected by its nilradical and prove that many classes of nilpotent Lie algebras (Einstein nilradicals, algebras with less th...
متن کاملA Nonstandard Ideal of a Radical Banach Algebra of Power Series
and, of course, the zero ideal. Such ideals are referred to as standard ideals. Any other closed ideals are denoted nonstandard ideals. It has been an open question for some time whether there exists any algebra weight {w(n)} such that ^(^(n)) contains a nonstandard ideal [6, p. 189], and the problem seems to go back to Silov (a proposed solution appearing in the literature [6, p. 205] is in er...
