Dear friends and alumni of ICERM,
We're in the midst of an exciting fall program in High Dimensional Approximation, and looking forward to the spring program in Emergent Phenomena and Phase Transitions. We are accepting applications to participate in this program and its workshops, so please take a moment to learn more about it below.
The fall has been unusually busy as we've also had our NSF site visit in September for ICERM's 2015-2020 renewal proposal. I look forward to sharing information with you about our future plans next spring. In the meantime, you can read about our many upcoming programs and opportunities for early career researchers in this newsletter, and perhaps learn a few new things about ICERM.Sincerely,
Spring 2015 Semester Program
Phase Transitions and Emergent PropertiesFebruary 2 - May 8, 2015
Emergent phenomena are properties of a system of many components which are only evident or even meaningful for the collection as a whole. A typical example is a system of many molecules, whose bulk properties may change from those of a fluid to those of a solid in response to changes in temperature or pressure. The basic mathematical tool for understanding emergent phenomena is the variational principle, most often employed via entropy maximization. The difficulty of analyzing emergent phenomena, however, makes empirical work essential; computations generate conjectures and their results are often our best judge of the truth.
The semester will include three workshops that will concentrate on different aspects of current interest, including unusual settings such as complex networks and quasicrystals, the onset of emergence as small systems grow, and the emergence of structure and shape as limits in probabilistic models. The workshops will (necessarily) bring in researchers in combinatorics and probability as well as statistical physics and related areas.

ICERM Seeks New Director
The institute's Board of Trustees and Brown University seek a new director of ICERM for an appointment to begin between August 2015 and July 2016. The Director will serve as the scientific and administrative leader of the institute and will be a distinguished member of the Brown faculty.
The successful candidate will possess outstanding scholarly credentials, including a Ph.D., as well as demonstrated academic leadership experience. The Director will hold a tenured position at Brown University in the Department of Mathematics or the Division of Applied Mathematics, or jointly in at least one of these departments. Preference will be given to applicants whose research interests align with the mission of ICERM. Although the Director will have no formal teaching obligations, the Director's faculty appointment will carry some expectation of service both to the department(s) in which the Director is appointed and to the university. The term of the appointment as Director of ICERM ends August 2020, and may be renewed.
The search committee consists of members of the ICERM Board of Trustees and faculty in Mathematics and Applied Mathematics.
For more information, please go to our job posting.
ICERM is currently seeking proposals for its 8-week undergraduate research program: Summer@ICERM.
A 2-3 page document which identifies one faculty leader and potential partner(s), a short description of the focus of the program, and a sample list of 8-10 research projects suitable for undergraduates. Preference will be given to proposals that relate to one of the semester program themes occurring in the adjacent spring or fall semester.
For more details about the proposal process and associated deadlines, please visit our "How to propose a Program" website.

Fall 2015 Semester Program
Computational Aspects of the Langlands ProgramSeptember 9, 2015 - December 4, 2015
In the late 1960s, Robert Langlands discovered a unifying principle in number theory providing a vast generalization of class field theory to include nonabelian extensions of number fields. This principle gives rise to a web of conjectures called the Langlands program which continues to guide research in number theory to the present day. For example, an important first instance of the Langlands program is the modularity theorem for elliptic curves over the rational numbers, an essential ingredient in the proof of Fermat's last theorem.
Despite its many successes, the Langlands program remains vague in many of its predictions, due in part to an absence of data to guide a precise formulation away from a few special cases. In this thematic program, we will experiment with and articulate refined conjectures relating arithmetic-geometric objects to automorphic forms, improve the computational infrastructure underpinning the Langlands program, and assemble additional supporting data. Such data has proven valuable for researchers in number theory, and it will continue to be made available at the L-Functions and Modular Forms Database.
During the semester we will focus on three specific aspects of the Langlands program. First, we will look at elliptic curves over number fields and genus 2 curves over the rationals and will consider their relationship to modular forms. Second, we will consider computational aspects of modular forms in higher rank. Specifically, we will examine K3 surfaces and their connections to modular forms on orthogonal groups. Our third topic concerns analytic aspects of L-functions, building upon and complementing the algebraic, arithmetic, and geometric data.Organizing Committee:

Spring 2016 Semester Program
Dimension and DynamicsFebruary 1 - May 6, 2016
Since its introduction by Felix Hausdorff in 1919, the concept of the Hausdorff dimension of sets and measures has been a versatile and powerful tool in classical analysis, geometry and geometric measure theory, mathematical physics and numerous applications. However, there has been a particularly important symbiosis between dynamical systems and dimension theory. This connection arises both from application of dimension theory to the classification and geometric analysis of dynamical systems (and their invariant sets and measures), and the fact that many classical objects of study in mathematics arise from (sometimes implicit) dynamical systems, which often play a role in the dimension theory of said objects.
Recently, there has been substantial progress on a number of central problems in dimension theory, and while many old problems remain, many new ones have also presented themselves. These include a deeper understanding of the relationship between dimension, entropy and Lyapunov exponents; the recent strengthenings of the Marstrand projection theorem and its implications for dimensions of sums of Cantor sets and the connections with number theory; multifractal analysis of ergodic averages, particularly the recent advances for multiple ergodic averages; and improved computational methods for obtaining effective bounds on Hausdorff dimension. This proposed program aims to set the stage for further progress on the many open problems in the field.
It is a challenging classical problem to compute numerically dimensions of given fractals. In recent years, computer-aided proofs in mathematical analysis have gained an increasing presence in mathematical research. One reason for this field's growing impact is due to its ability to produce high-quality quantitative information about global, nonlinear problems. As a consequence, solutions to a large class of previously intractable problems are now within reach, and recently several long-standing conjectures have been verified using rigorous computations.
During the semester we will focus on three specific aspects of the interaction between these two areas: (i) ergodic, algebraic and combinatorial methods in dimension theory; (ii) computations in fractal geometry in dynamical systems; and (iii) fractal geometry and hyperbolic dynamics.Organizing Committee:
