Relative double commutants in coronas of separable C*-algebras

We prove a double commutant theorem for separable subalgebras of a wide class of corona C*-algebras, largely resolving a problem posed by Pedersen. Double commutant theorems originated with von Neumann, whose seminal result evolved into an entire field now called von Neumann algebra theory. Voiculescu later proved a C*-algebraic double commutant theorem for subalgebras of the Calkin algebra. We prove a similar result for subalgebras of a much more general class of so-called corona C*-algebras

Tame stacks in positive characteristic

We introduce and study a class of algebraic stacks with finite inertia in positive and mixed characteristic, which we call tame algebraic stacks. They include tame Deligne-Mumford stacks, and are arguably better behaved than general Deligne-Mumford stacks. We also give a complete characterization of finite flat linearly reductive schemes over an arbitrary base. Our main result is that tame algebraic stacks are \'etale locally quotient by actions of linearly reductive finite group schemes. In a subsequent paper we will show that tame algebraic stacks admit a good theory of stable maps.Comment: 31 pages, 3 sections and 1 appendi

The Income Gap Between Natives and Second Generation Immigrants in Sweden: Is Skill the Explanation?

This is the first study to use an achievement test score to analyze whether the income gap between second-generation immigrants and natives is caused by a skill gap rather than ethnic discrimination. Since, in principle, every male Swedish citizen takes the test when turning 18, we are able to bring more evidence to bear on the matter by estimating the income gap for a very large sample of individuals who are of the same age and have the same years of schooling at the test date. Once the result of the Swedish Military Enlistment Test is controlled for, the income gap almost disappears for second generation immigrants with both parents born in Southern Europe or outside Europe. However, when using a regular set of control variables the income gap becomes overestimated. This difference in results is most likely explained by the fact that schooling is a bad measure of productive skills for these groups of second-generation immigrants. It indicates that they compensate for their lower probability of being employed by investing in (in relation to their skill level) more schooling than otherwise similar natives.Productive skills, discrimination, incomes, wages
