Cycle symmetries and circulation fluctuations for discrete-time and continuous-time Markov chains
Haldane equality current fluctuations fluctuation theorems
2014/12/5
In probability theory, equalities are much less than inequalities. In this paper, we find a series
of equalities which characterize the symmetry of the forming times of a family of similar cycles

Applications to the University of Cambridge rose 2% in 2012 despite the introduction of higher fees by the UK Government, according to undergraduate admissions statistics published today.
The Streaming Complexity of Cycle Counting, Sorting By Reversals, and Other Problems
Streaming Complexity Cycle Counting,
2012/12/3
In this paper we introduce a new technique for proving streaming lower bounds (and one-way communication lower bounds), by reductions from a problem called the Boolean Hidden Hypermatching problem (BH...
Optimal phase response curves for stochastic synchronization of limit-cycle oscillators by common Poisson noise
Euler-Lagrange equation phase response curve limit-cycle oscillators Poisson noise
2011/7/6
We consider optimization of phase response curves for stochastic synchronization of non-
interacting limit-cycle oscillators by common Poisson impulsive signals. The optimal functional
shape for suf...
Accelerating cycle expansions by dynamical conjugacy
Accelerating cycle dynamical conjugacy Periodic orbit theory zeta function spectral determinant
2011/7/5
Periodic orbit theory provides two important functions—the dynamical zeta function and the
spectral determinant for the calculation of dynamical averages in a nonlinear system. Their cycle
expansion...

H. Davenport's Problem asks: What can we expect of two polynomials,over Z, with the same ranges on almost all residue class elds?This stood out among many separated variable problems posed by Davenpo...
Critical Ising Model and Cycle Rooted Spanning Forests: an explicit correspondence
Critical Ising Model Cycle Rooted Spanning Forests explicit correspondence
2011/2/24
Fisher established an explicit correspondence between the 2-dimensional Ising model defined on a graph G and the dimer model defined on a decorated version G of this graph [Fis66]. In this paper, we p...
The diagonal of tropical matroid varieties and cycle intersections
diagonal of tropical matroid varieties cycle intersections
2011/2/21
We define an intersection product of tropical cycles on matroid varieties (via cutting out the diagonal) and show that it is well-behaved. In particular, this enables us to intersect cycles on moduli ...

2011/3/2
We investigate relations between di erent width parameters of graphs, in particular balanced sepa-rator number, treewidth, and cycle rank.

Critical Ising Model Cycle Rooted explicit correspondence
2011/3/4
Fisher established an explicit correspondence between the 2-dimensional Ising model defined on a graph G and the dimer model defined on a decorated version G of this graph [Fis66].
Asymptotic Limit of a Singularly Perturbed Stationary Diffusion Equation: The Case of a Limit Cycle
Diffusion Equation Limit Cycle
2010/11/23
A limit cycle for a nonlinear ordinary differential equation has a sustained, stationary oscillation in time; Any non-trivial stationary stochastic process also exhibits stationary oscillations in tim...
Limit cycle's uniqueness for second order O.D.E.'s polynomial in $\dot x$
Limit cycle's uniqueness O.D.E.'s polynomial
2010/11/12
We prove a uniqueness result for limit cycles of the second order ODE $\ddot x + \sum_{j=1}^{J}f_{j}(x)\dot x^{j} + g(x) = 0$. We extend a uniqueness result proved in \cite{CRV}. The main tool applied...
Enumeration of snakes and cycle-alternating permutations
snakes cycle-alternating permutations
2010/11/9
Springer numbers are an analog of Euler numbers for the group of signed permutations. Arnol'd showed that they count some objects called snakes, that generalize alternating permutations. Hoffman estab...

cycle decompositions Markov chains biochemical applications
2010/12/10
We slightly extend the fluctuation theorem obtained in [24] for sums of generators, considering continuous–time Markov chains on a finite state space whose underlying graph has multiple edges and no l...
Injectivity of a certain cycle map for finite dimensional W-algebras
Injectivity certain cycle map finite dimensional W-algebras
2010/12/6
We study a certain cycle map defined on finite dimensional modules for the W-algebra with regular integral central character. Via comparison with the theory in postive characteristic, we show that thi...
