This talk will focus on the embedding problem: given two subshifts, under what conditions can one be embeded into the other? We will start with the classical Krieger embedding theorem which give criteria for embedding a subshift into a mixing SFT. We...

For a noisy channel, the stationary capacity is the supremum of information rates achievable by stationary input processes. The Markov capacity of a given order is the supremum of information rates achievable by stationary Markov input processes of...

The method of cutting and stacking has long been used in ergodic theory. As a useful tool for constructing stationary and ergodic processes with desired properties, this method should also be powerful in solving information theoretic problems. In...
