报告摘要：Given a discrete metric space X with bounded geometry, we can associate it with a C*-subalgebra of B(l^2(X)), called the uniform Roe algebra of X which plays an important role in higher index theory. For any p greater than or equal to 1, we can similarly consider the l^p uniform Roe algebra of X as a Banach subalgebra of B(l^p(X)). A natural question is if the K-theory of l^p uniform Roe algebras depends on p? In ongoing work with Dapeng Zhou, we study this question for metric spaces which admit a coarse embedding into finite dimensional Hilbert space.
