A finite element space of functions is then defined by taking the continuous functions on ℝh which are linear affine on each simplex of the polygonal surface. We use surface gradients to define weak ...

The linear–quadratic mean field social control problem is studied in a large-population system with heterogeneous agents following the direct approach. A graph is introduced to represent the network ...

Under the influence of nonlinearity, time-varying delay, and uncertainty, the consensus problem is concerned in this study for multiagent systems modeled by partial differential equations, which means ...
