Embedding of reversible Markov matrices
Ellen Baake, Michael Baake, Jeremy Sumner
The embeddability of reversible Markov matrices into time-homogeneous Markov semigroups is revisited, with some focus on simplifications and extensions. In particular, we do not de…

On the algebra of equal-input matrices in time-inhomogeneous Markov flows
Michael Baake, Jeremy Sumner
Markov matrices of equal-input type constitute a widely used model class. The corresponding equal-input generators span an interesting subalgebra of the real matrices with zero row…
