Assessing Lagrangian coherence in atmospheric blocking Open
Atmospheric blocking exerts a major influence on mid-latitude atmospheric circulation and is known to be associated with extreme weather events. Previous work has highlighted the importance of the origin of air parcels that define the bloc…

Characterizing Nonuniform Hyperbolicity by Mather-Type Admissibility Open
We consider linear cocycles acting on Banach spaces which satisfy the assumptions of the multiplicative ergodic theorem. A cocycle is nonuniformly hyperbolic if all Lyapunov exponents are non-zero, which is equivalent to the existence of a…

A mathematical perspective on Romanisation: Modelling the Roman road activation process in ancient Tunisia Open
Romanisation is a multi-faceted historical phenomenon with profound and lasting cultural impact on the ancient world. In the modern-day territory of Tunisia, this is particularly manifest during the first four centuries AD, under the reign…

Random attractors on countable state spaces Open
We study the synchronization behavior of discrete-time Markov chains on countable state spaces. Representing a Markov chain in terms of a random dynamical system, which describes the collective dynamics of trajectories driven by the same n…

Extracting coherent sets in aperiodically driven flows from generators of Mather semigroups Open
Coherent sets are time-dependent regions in the physical space of nonautonomous flows that exhibit little mixing with their neighborhoods, robustly under small random perturbations of the flow. They thus characterize the global long-term t…

Continuous-time extensions of discrete-time cocycles Open
We consider linear cocycles taking values in driven by homeomorphic transformations of a smooth manifold, in discrete and continuous time. We show that any discrete-time cocycle can be extended to a continuous-time cocycle, while preservi…

Continuous-time extensions of discrete-time cocycles Open
We consider linear cocycles taking values in $\textup{SL}_d(\mathbb{R})$ driven by homeomorphic transformations of a smooth manifold, in discrete and continuous time. We show that any discrete-time cocycle can be extended to a continuous-t…
View article: Sensitivity of steady states in networks with application to Markov chains and chemical reaction networks
Sensitivity of steady states in networks with application to Markov chains and chemical reaction networks Open
We consider steady states of dynamics that have an underlying network structure. We study how a steady state responds to small perturbations in the network parameters and how this sensitivity is connected to the network structure. We intro…
