Arnaud Brothier, Vanderbilt University (USA) will give a talk with title: Analytic properties for subfactors

Abstract:

I will discuss analytic properties for groups and their generalizations to subfactors, standard invariants, and certain tensor categories.

I will present a class of subfactor planar algebras that are constructed with a group acting on a bipartite graph.

I will show that if the group satisfies a given approximation property (such as amenability, Haagerup property, or weak amenability), then the subfactor planar algebra satisfies it as well.

I will exhibit an infinite family of subfactor planar algebras with non-integer index that are non-amenable, have the Haagerup property, and have the complete metric approximation property.

PIV investigation of the flow structures developing in a parallel valves Diesel engine cylinder during the intake stroke.  

In this talk I will present the Real algebraic K-theory construction of Hesselholt and Madsen, and discuss some on-going joint work with Ib Madsen. Real algebraic K-theory is a functor that to a ring A with anti-involution associates a genuine C_2-equivariant spectrum KR(A). Here C_2 denotes the cyclic group of order two. The underlying spectrum of KR(A) has the homotopy type of K(A), the usual K-theory space of A in the sense of Quillen, and the C_2-fixed point spectrum is weakly equivalent to the Hermitian K-theory of A. I will talk about generalizations of known theorems for algebraic K-theory to KR, including delooping results, "fundamental" theorems and group completion.

The issue of inequality has moved to the top of the policy agenda around the world. Many see the Welfare State, the most important bulwark against the increase in inequality, as under threat. What do we see as the pillars of the 21st Century welfare state?
