具有牛顿位势的凝聚方程

The aggregation equation with Newtonian potential

Elaine Cozzi, Gung-Min Gie, James P Kelliher

摘要:

具有牛顿位势的粘性和非粘性聚集方程模拟了许多不同的物理系统,并且在二维不可压缩流体力学中具有密切的类似物。我们考虑这些方程在整个空间中的轻微推广,建立粘性方程的适定性和空间衰减,并获得当粘性趋于零时粘性解收敛于无粘解。

英文摘要:

The viscous and inviscid aggregation equation with Newtonian potential models a number of different physical systems, and has close analogs in 2D incompressible fluid mechanics. We consider a slight generalization of these equations in the whole space, establishing well-posedness and spatial decay of the viscous equations, and obtaining the convergence of viscous solutions to the inviscid solution as the viscosity goes to zero.
