Chow group of 0-cycles on a surface over a p-adic field with infinite torsion subgroup

In this talk I would like to demonstrate how Hodge theory can play a crucial role in an arithmetic question. The issue is to construct an example of a projective smooth surface X over a p-adic field K such that for any prime   more››

Adaptive evolution and concentrations in parabolic PDEs

Living systems are subject to constant evolution. Their environment can be considered as a nutrient shared by all the population. This allows certain individuals, characterized by a ‘physiological trait’, to expand faster because they are bett   more››

Minimal determinants for the centres and topological centres of some

The algebraic centre of the uniformly continuous compactification GUC of an abelian locally compact group G is G itself. There is a stronger result: if u commutes with just two (carefully chosen) elements of   more››

Hardy's Uncertainty Principle for Lie Groups

A classical theorem due to Hardy says that a non-zero measurable function on the real line and irs Fourier transform cannot both have very strong exponential decay. Hardy's theorem also holds for Rn, and during the past ten years there   more››

On braided and ordinary Hopf algebras

Braided Hopf algebras occur naturally in the structure theory of ordinary Hopf algebras. I will show how they arise in this context and how they can be used to construct (and possibly to classify) ordinary finite dimensional Hopf algebras.   more››

Mathematical Modelling of Host-Parasitoid Systems: Spatio-Temporal Dynamics

Parasitoids are a specialised class of predators that use a single prey or host for their juvenile development but unlike parasites kill the host as a result of this development. Within this lifestyle there are many variations in life history that   more››

The Reality of Computer Models: Statistics and Virtual Science

Computer models are imperfect representations of real phenomena. An austere view is that validating a model cannot be done, the "primary value of models is heuristic: models are representations, useful for guiding further study but not suscep   more››

Habitat use and movements of plains zebra in response to predation

Prey species must adapt their behavior to avoid predation while meeting resource needs. In East Africa savannah, plains zebra are a key prey for lions. We study a population of 600 plains zebra in Ol Pejeta Conservancy, Kenya. We test how zebra mo   more››

PIMS Probability Seminar 2006

If we would -say- estimate the anthropogenic contribution to climate change, we would have to understand the range of natural variability. Now, the climate of the Earth is an experiment, which is only run once, so in order to assess this we have t   more››

Overview of a Methodology for Developing and Assessing Simulation Models of Complex Systems

Prediction of dispersal and establishment of aquatic nonindigenous species across Ontario lakes: Linking vector-based and habita

Prediction of range expansion of nonindigenous species is important, as it is often easier to prevent invasions than to mitigate impacts once invasions have occurred. A combination of models for propagule pressure (gravity models) and habitat matc   more››

Spatiotemporal patterns in models of biological invasion and epidemic spread

This seminar is intended to give an informal overview of my previous work and some recent ideas. I am especially interested in patterns of spatiotemporal dynamics that are induced by the joint interplay of spatial spread, demographics (e.g., Allee   more››
