| Rates of Convergence for 'Features' of a Markov Chain | Approximate Counting, Markov Chains and Phase Transitions | 2016-02-22 |
Shows that many natural features mix far faster than global distance: simple walk on Z_p mixes a half-circle feature in p squared steps but parity in O(1)… | ||
| Some Probabilistic Uses of Dirichlet Eigenvectors | Spectral Algorithms: From Theory to Practice 2014 | 2014-10-27 |
Proves quantitative rates of convergence to the quasi-stationary distribution for absorbing chains, gives the closed-form cosine law on a path and shows… | ||
| Carries and Cocycles | Neo-Classical Methods in Discrete Analysis 2013 | 2013-12-02 |
Adds digits produce carries with probability 1/2 − 1/(2b) (45% when b = 10); choosing balanced coset representatives cuts forced carries to (b^2 − 1)/4 (≈… | ||
