Van T. Cyr Olin 361 Department of Mathematics Bucknell University Lewisburg, PA 17837, USA [email protected] www.facstaff.bucknell.edu/vtc004 Citizenship United States of America Research Interests Dynamical systems, ergodic theory, combinatorics. My work is in symbolic dynamics and has focused in three areas: thermodynamic formalism for countable state Markov shifts, algebraic properties of the automorphism group of zero entropy subshifts, and Nivat’s conjecture on Z2 symbolic systems.
