Talk Title]

Modeling and predicting urban crime – How data assimilation helps bridge the gap between stochastic and continuous models

Abstract]

Data assimilation is a powerful tool for combining mathematical models with real-world data to make better predictions and estimate the state and/or parameters of dynamical systems. In this talk I will give an overview of some work on models for predicting urban crime patterns, ranging from stochastic models to differential equations. I will then present some work on data assimilation techniques that have been developed and applied for this problem, so that these models can be joined with real data for purposes of model fitting and crime forecasting.

Second talk title]

Game Theoretical Model of Religious Group Evolution

Second talk abstract]

Religious groups produce collective goods. The group’s production is
increasing in members’ contributions. Religious services can be represented
by a unidimensional trait called "strictness", that dictates the minimum
contribution of members. Individuals may have preferences on religious
groups of certain strictness levels, but they only can switch to such group
if they've been sufficiently exposed to it previously. In this talk, we
present a model about the evolution of populations of religious affiliations
with different strictness levels and some analytical results of
2-affiliation case.
