报告摘要：In this talk, we briefly discuss three topics such as the universality of the collective dynamics,second-order Cucker-Smale flocking on Riemannian manifolds and a generalized aggregation model for the ensemble of rank-m tensors with the same size. In ourfirst story, we discuss universal triality relation between bacteriaaggregation, Cucker-Smale flocking and Kuramoto synchronization. These three seemingly different phenomena can be integrated into a common nonlinear consesnsus framework. In our second story, we present a second-order Cucker-Smale modeling on Riemannian manifolds such as the unit circle, the unitsphere in R^2 and Poincare upper half plane model for hyperbolic geometry.Finally, in our third story, we introduce a new unified model for the ensembleof aggregation of tensors with the same rank and size. Our new model include sprevious well-known mathematical models such as the Kuramoto model, the Lohetype models as special cases.
