Mid Atlantic Numerical Analysis Day 2014
A conference on numerical analysis and scientific computing for graduate students and postdocs from the Mid-Atlantic region.

Eitan Tadmor, Social Dynamics: Modeling, Analysis and Numerical SimulationAbstractWe discuss the dynamics of systems of "agents" which are self-propelled by 'environmental averaging', namely, dynamics driven by the engagement of agents with their 'local neighbors.' Prototype examples include opinion dynamics in human networks, flocking, swarming and bacterial self-organization in biological organisms or rendezvous in mobile systems. Two natural questions arise in this context: what happens when the time T tends to infinity and when the number of agents N tends to infinity. The underlying issue is how different "rules of engagement" influence the formation of clusters realized as Dirac masses, and in particular, the tendency to concentrate into one cluster, reflecting a "consensus of opinions." We shall discuss several key models, present the analysis of their large time formation of Dirac masses and describe numerical novel numerical methods, DG-based and velocity rescaling to simulate such Dirac masses. |
The Conference
This one-day meeting will start at 10am to allow same-day travel.
It will be held in Room 617 Wachman Hall, Temple University, 1805 North Broad street, just north of Montgomery Avenue (see directions on right margin).
It will be an opportunity for graduate students and postdocs to present their research, and to meet other researchers.
There will be contributed talks and a poster session.
There will be no registration fee. In order to guarantee appropriate space in the lecture rooms, we ask every participant to please register in advance, even if you are not planning to give a talk.
Lunch will be provided.
