The Countable Chain Condition for C*-Algebras
In this paper, we introduce the countable chain condition for C*-algebras and
study its fundamental properties. We show independence from ZFC of the
statement that this condition is preserved under the tensor products of
C*-algebras.Comment: 9 page
Strong Stationary Duality for M\"obius Monotone Markov Chains: Unreliable Networks
For Markov chains with a partially ordered finite state space we show strong
stationary duality under the condition of M\"obius monotonicity of the chain.
We show relations of M\"obius monotonicity to other definitions of monotone
chains. We give examples of dual chains in this context which have transitions
only upwards. We illustrate general theory by an analysis of nonsymmetric
random walks on the cube with an application to networks of queues
