We present a general construction of a family of ordinal
sums of a sequence of structures and prove an elimination
theorem for the class of ordinal sums in an expanded language.
From this we deduce...

2015/8/26
This paper develops bounds on the rate of decay of powers of Markov kernels
on finite state spaces. These are combined with eigenvalue estimates to give
good bounds on the rate of convergence to sta...
