### Game of alignment: collective behavior of multi-species

Abstract:

In this talk, I will present a recent result concerning the long-time dynamics of multi-species alignment model. What distinguishes the different species is the protocol of their interaction with the rest of the crowd: the collective motion is described by different communication kernels, $\phi_{\alpha\beta}$, between the crowds in species $\alpha$ and $\beta$. We show that flocking of the overall crowd emerges provided the communication array between species forms a connected graph. This is a joint work with Eitan Tadmor.
