The conditioning of GFEM could be worse than the standard FEM.We will show that if the angle between the underlying piecewise linear FE space and the enrich
In this mini-symposium,we will mainly discuss new developments and open questions concerning the approximation of singular solutions of partial differential
The Monge-Ampère equation is a nonlinear partial differential equation with a geometric theory due to Aleksandrov.Solutions of the Monge-Ampère equation a
In this paper,we modify the classical social force model to be more realistic in the emergent situations,and use it to investigate the crowd panic under ful
This paper proposes an optimization-based collision avoidance model for pedestrian dynamics.In this model,the behaviors of pedestrians are governed by their
The averaging theory is a fundamental tool to investigate the stability of time-varying systems.The application of averaging theory to the field of consensu
Cooperators that refuse to participate in sanctioning defectors create the second-order free-rider problem.Such cooperators will not be punished because the
