Finite dimensional approximations and deformations of group C*-algebras
<p>Quasidiagonality is a finite-dimensional approximation property of a <em>C</em>*-algebra which indicates that it has matricial approximations that capture the structure of the <em>C</em>*-algebra. We investigate when <em>C</em>*-algebras associated to discrete groups have such a property with …

Nonunital multiplier pairs and remarks on generalized group C*-algebras
… on f or g, B (f, g) will be nuclear, weakly quasidiagonal and we will be able to compute its Ext group. In the last two sections we will give a partial description of the K1-group of B (f, g) and then using the results from [DH] calculate the free entropy dimension of B (f, g).</p><p>In the …
