Articles in Mathematics Research Reports are freely available for a world-wide audi- ence, with no author publication charges (diamond open access) but high production value, thanks to financial support from the Anatole Katok Center for Dynamical Sys- tems and Geometry at the Pennsylvania State University and to the infrastructure of the Centre Mersenne. The articles in MRR are research announcements of significant ad- vances in all branches of mathematics, short complete papers of original research (up to about 15 journal pages), and review articles (up to about 30 journal pages). They communicate their contents to a broad mathematical audience and should meet high standards for mathematical content and clarity. The entire Editorial Board approves the acceptance of any paper for publication, and appointments to the board are made by the board itself. -

August 3, 2020 Dr. Robert Zimmer President University of Chicago 5801 South Ellis Ave., Suite 501 Chicago, Illinois 60637 Dear Dr. Zimmer: We write to further understand the effects of adversarial foreign direct investment in the U.S. higher education system.1 Under Secretary Betsy DeVos’s leadership, the Department of Education (Department) has sought to improve transparency and reduce reliance on foreign investment by actively enforcing Section 117 of the Higher Education Act of 1965, which requires colleges and universities to disclose contracts with, and gifts from, any foreign source of over $250,000 to the Department.2 To date, the Department has uncovered over $6.5 billion of previously unreported foreign donations to U.S. Institutes of Higher Education (IHE).3 On May 20, 2020, the Department briefed the Oversight Committee about this apparent lack of transparency in reporting as required by the law. The Department also raised concerns about this level of IHEs dependency on foreign funding from adversarial states and the inherent national security risks.4 Through the efforts of the Department, the Committee learned that many countries use donation agreements or contracts (agreements) with IHEs, professors, or researchers (recipients) to leverage their money into some type of benefit, or quid pro quo.5 This benefit can materialize in different ways. For example, Qatar deems all its donations to recipients to be “strategic” and “trade secrets” and precludes the recipient from disclosing the amount or purpose of the donation.6 Furthermore, some countries place clauses in their agreements granting them first right of refusal before the recipient publishes or sells any work product.7 Finally and most concerning, some recipients alter their decision making based on the donations received.8 During the briefing, the Department informed the Committee that after reports the COVID-19 pandemic may be the result of negligence in a lab in Wuhan, China, two universities that have 1 Letter from Jim D. -
Chicago Physics One
CHICAGO PHYSICS ONE 3:25 P.M. December 02, 1942 “All of us... knew that with the advent of the chain reaction, the world would never be the same again.” former UChicago physicist Samuel K. Allison Physics at the University of Chicago has a remarkable history. From Albert Michelson, appointed by our first president William Rainey Harper as the founding head of the physics department and subsequently the first American to win a Nobel Prize in the sciences, through the mid-20th century work led by Enrico Fermi, and onto the extraordinary work being done in the department today, the department has been a constant source of imagination, discovery, and scientific transformation. In both its research and its education at all levels, the Department of Physics instantiates the highest aspirations and values of the University of Chicago. Robert J. Zimmer President, University of Chicago Welcome to the inaugural issue of Chicago Physics! We are proud to present the first issue of Chicago Physics – an annual newsletter that we hope will keep you connected with the Department of Physics at the University of Chicago. This newsletter will introduce to you some of our students, postdocs and staff as well as new members of our faculty. We will share with you good news about successes and recognition and also convey the sad news about the passing of members of our community. You will learn about the ongoing research activities in the Department and about events that took place in the previous year. We hope that you will become involved in the upcoming events that will be announced. -

Commensurated Subgroups of Arithmetic Groups, Totally
COMMENSURATED SUBGROUPS OF ARITHMETIC GROUPS, TOTALLY DISCONNECTED GROUPS AND ADELIC RIGIDITY YEHUDA SHALOM AND GEORGE A. WILLIS 1. Introduction The Margulis-Zimmer conjecture. The subject of this paper is a well known ques- tion advertised by Gregory Margulis and Robert Zimmer since the late 1970’s, which seeks refinement of the celebrated Normal Subgroup Theorem of Margulis (hereafter abbreviated NST). Although Margulis’ NST is stated and proved in the context of (higher rank) irreducible lattices in products of simple algebraic groups over local fields, by Margulis’ arithmeticity theorem we may and shall work solely in the framework of (S-)arithmetic groups. One departure point for the Margulis-Zimmer conjecture is the phenomenon that while all higher rank S-arithmetic groups are uniformly treated by the NST, there is a notable difference in the structure of subgroups which are commensu- rated, rather than normalized, by the ambient arithmetic group. For example, the group 1 SLn(Z[ p ]) commensurates its subgroup SLn(Z), while the latter commensurates no ap- parent infinite, infinite index subgroup of its own. The obvious generalization of this example, which by Margulis arithmeticity theorem and with the aid of the restriction of scalars functor is the most general one, goes as follows: Definition 1.1. Let K be a global field, its ring of integers, and let G be an ab- solutely simple, simply connected algebraicO group defined over K. Let V be the set of all inequivalent valuations on K, and let V ∞ V denote the archimedean ones. For a subset V ∞ S V , let K be, as usual,⊂ the ring of S-integers in K, and let ⊆ ⊆ OS ⊆ Γ < G(K) be an S-arithmetic group, namely, a subgroup commensurable with G( S). -

Some Thoughts on Undergraduate Education for Highly Selective Universities Jonathan R. Cole Columbia University “In the beginning, there was Hopkins” A Very Special Place: The First Major Research University (1876) “It is one of the noblest duties of a university to advance knowledge, and to diffuse it not merely among those who can attend the daily lectures but far and wide.” Daniel Coit Gilman “Our history shows that our commitment to bold experimentation did not pass with our founding. It’s at the core of who we are.” “Be vigorous, bold, and smart in championing the truths you have discovered and hold dear.” Ronald Daniels Hopkins in historical and social context ■ Roughly 7,000 colleges and universities in the United States ■ Only somewhat over 100 highly intensive research universities ■ Different strokes for different folks ■ Curriculum should dovetail well with the identity of the university and represent a realization of its basic principles and goals ■ Hopkins Mission Statement: “The mission of the Johns Hopkins University is to educate its students and cultivate for lifelong learning, to foster independent and original research, and to bring the benefits of discovery to the world” Getting In and the Curriculum: Shaping a class ■ Bringing the faculty back in ■ The quest for the quirky and diversity of every kind ■ How this is linked to the curriculum Implications : • Who studies history today? • Foreign languages? • Do the subalterns speak to our students? • Is the C.P.
