Osher, Chair In this dissertation, we provide efficient algorithms for modeling the behavior of a single agent, multiple agents, and a continuum of agents. For a single agent, we combine the modeling framework of optimal control with advances in optimization splitting in order to efficiently find optimal paths for problems in very high-dimensions, thus providing allevia- tion from the curse of dimensionality. For a multiple, but finite, number of agents, we take the framework of multi-agent reinforcement learning and utilize imitation learning in order to decentralize a centralized expert, thus obtaining optimal multi-agents that act in a de- centralized fashion. For a continuum of agents, we take the framework of mean-field games and use two neural networks, which we train in an alternating scheme, in order to efficiently find optimal paths for high-dimensional and stochastic problems.

We received a no-cost extension to allow us to spend unused funds after August 31, 2015. We estimate that about a third of our activities in 2015-16 were supported by the remaining funds from this grant; therefore we are including the first four months (through Dec. 31, 2015) of the 2015-16 year in this report. This report, then, covers IPAM’s activities taking place between Sept. 1, 2014, and December 31, 2015 (which we will refer to in this report as the reporting period). IPAM held three long programs during the reporting period. Each long program included tutorials, several workshops, and a culminating retreat. Between workshops, the participants planned a series of talks and focus groups.

I left it immediately and switched to numerical analysis after my thesis. I was lucky enough to talk to some people, including Peter Lax, who suggested the numerical stuff. I: Did you find your real inclinations in applied mathematics? O: Yeah, but it did not happen until after I got my degree. I liked everything and I specialized more after my PhD. I: Did you use functional analysis later on in your work? O: Yes. The first thing I did in numerical analysis was an application of Toeplitz Matrices. It used functional analysis and was short and elegant. I: You switched to applied mathematics and then eventually to something very practical like applying to movie animation.

    FALL 2014 CommonTHE Denominator UCLA DEPARTMENT OF MATHEMATICS NEWSLETTER Stanley Osher Receives Prestigious Gauss Prize Stanley Osher, UCLA mathematics professor since 1977, is the proud recipient of the Carl Friedrich Gauss Prize, considered the highest honor in the field of applied mathematics. Named for 19th century mathema- tician Carl Friedrich Gauss and presented every four years, the prize was first awarded at the 2006 International Congress of Mathematics (ICM). Previous recipients were Kiyoshi Ito in 2006 and Yves Meyer in 2010, two of Stan’s personal scientific heroes. The prize was awarded in Seoul, South Korea, during the opening ceremony for the 2014 ICM. The Gauss Prize is awarded jointly by the International Mathematical Union and the German Mathematical Society for “outstanding math- ematical contributions that have found significant applications outside of mathematics.” Referred to as “a one-man bridge between advanced mathematics and practical real world problems,” Stan has repeatedly Stan Osher accepts the Gauss created new tools and techniques that traverse barriers between re- Prize from the President of search and the world in which we live.

The workshop was held at the Institute for Pure and Applied Mathematics (IPAM) at UCLA on October 12-14, 2011. It involved 23 invited scientists and 4 government observers. 1. Executive Summary This report summarizes the Workshop on Future Directions in Mathematics, sponsored by the Office of the Assistant Secretary of Defense for Research and Engineering (ASD(R&E)), Basic Science Office. The workshop was held at the Institute for Pure and Applied Mathematics (IPAM) at UCLA on October 12-14, 2011. It involved 23 invited scientists and 4 government observers, listed in Appendix I. The goals of the workshop were to provide input to the ASD(R&E) on the current state of mathematics research, the most promising directions for future research in mathematics, the infrastructure needed to support that future research, and a comparison of mathematics in the US and in the rest of the world. These goals were articulated through a set of six questions, listed in Appendix II, that were sent to the participants prior to the workshop. The invited mathematical scientists came from universities and industrial labs, and included mathematicians, statisticians, computer scientists, electrical engineers and mechanical engineers.
