We prove almost everywhere convergence for convolutions of locally integrable functions with shrinking L^(1) dilations of a fixed integrable kernel with an integrable radially decreasing *** set on which the convergence holds is an explicit subset of the Lebesgue set of the locally integrable function of full *** result can be viewed as an extension of the Lebesgue differentiation theorem in which the characteristic function of the unit ball is replaced by a more general *** obtain a similar result for multilinear convolutions.

The broad goal of the research surveyed in this article is to develop methods for understanding the aggregate behavior of interconnected dynamical systems, as found in mathematical physics, neuroscience, economics, power systems and neural networks. Questions concern prediction of emergent(often unanticipated) phenomena, methods to formulate distributed control schemes to influence this behavior, and these topics prompt many other questions in the domain of learning. The area of mean field games, pioneered by Peter Caines, are well suited to addressing these topics. The approach is surveyed in the present paper within the context of controlled coupled oscillators.
