**Goals for the class:**

a) Learning the key ideas of calculus, which I call the six pillars.

1. Close is good enough (limits)

2. Track the changes (derivatives)

3. What goes up has to stop before is can come down (max/min)

4. The whole is the sum of the parts (integrals)

5. The whole change is the sum of the partial changes (fundamental theorem)

6. One variable at a time.

b) Learning how to analyze a scientific situation and model it mathematically.

c) Learning to analyze a mathematical model using calculus.

d) Learning how to apply the results of the model back into the real world.

e) Learning enough formulas and calculational methods to make other goals possible. There are three questions associated with every mathematical idea in existence:

1. What is it?

2. How do you compute it?

3. What is it good for?

Compared to most math classes, we're going to spend a lot more time on the first and third questions, but we still need to address the second. You can't spend all your time looking at the big picture! You need some practice sweating the details, too

## M 384C Mathematical Statistics I

**Description**

The two semesters of this course (M 384C and M 384D) are designed to provide a solid theoretical foundation in mathematical statistics.

During the TWO-SEMESTER course, the statistical topics include the properties of a random sample, principles of data reduction (sufficiency principle, likelihood principle, and the invariance principle), and theoretical results relevant to point estimation, interval estimation, hypothesis testing with some work on asymptotic results.

During the first semester, M384C, students are expected to use their knowledge of an undergraduate upper-level probability course and extend those ideas in enough depth to support the theory of statistics, including some work in hierarchical models to support working with Bayesian statistics in the second semester. Students are expected to be able to apply basic statistical techniques of estimation and hypothesis testing and also to derive some of those techniques using methods typically covered in an undergraduate upper-level mathematical statistics course. A brief review of some of those topics is included. Probability methods are used to derive the usual sampling distributions (min, max, the t and F distributions, the Central Limit Theorem, etc.) Methods of data reduction are also discussed, particularly through sufficient statistics. This includes the five chapters of the text and part of the sixth chapter as well as some additional material on estimation and hypothesis testing.

## M 392C (Ben-Zvi) Algebraic Geometry

**Description**

This will be a first course in modern algebraic geometry, largely following the textbook by Ravi Vakil, The Rising Sea: Foundations of Algebraic Geometry. Some familiarity with basics of category theory and commutative algebra recommended.

** **

## M 392C (Freed) Differential Geometry

**Description**

Differential geometry is the application of calculus to geometry on smooth manifolds. Felix Klein's Erlangen program defines geometry in terms of symmetry, and in the first part of the course we delve into its manifestation in smooth geometry. So we begin with basics about Lie groups and move on to the geometry of connections on principal bundles. We focus in particular on the bundle of frames and geometric structures on manifolds.

Armed with this general theory, we can move in many directions. Possible topics include Chern-Weil theory of characteristic classes; topics in Riemannian geometry, symplectic geometry, and spin geometry; differential equations on manifolds; curvature and topology. Students' interest will influence the particular topics covered.

**Prerequisites:** Familiarity with smooth manifolds and calculus on smooth manifolds at least at the level of the prelim class.

## M 392C (Kileel) Geometric Foundations of Data Science

This is a graduate topics course on geometric methods in data science. Data sets in applications often have interesting geometry. For example, individual data points might consist of images or volumes. Alternatively, the totality of the data may be well-approximated by a low-dimensional space. This course surveys computational tools that exploit geometric structure in data, as well as some of the underlying mathematics.

The syllabus will adapt to the interests of course participants, but we plan to survey some of the following topics:

- principal component analysis (including streaming PCA),
- tensor decomposition and latent variable estimation (higher-order PCA),
- clustering methods (k-means and mixture of Gaussians),
- non-linear dimensionality reduction (manifold learning),
- numerical optimization (semi-definite programming and possibly semi-algebraic optimization or manifold optimization).

Time permitting, we might look at applications of group theory in data science.

We will be reading excerpts from important papers and monographs. Students will present some fraction of the lectures (with coaching from the instructor), write up lecture notes, and submit a final project with a written report. For the project, students may choose between applying methods to real data sets or writing a synopsis of a theoretical paper. For real data sets, possible sources include signal processing, microscopy or computer vision applications, among others.

The course's main prerequisites are linear algebra, basic probability, and mathematical maturity. Programming familiarity (or willingness to learn) will help with certain projects. A few elements of differential and algebraic geometry will be developed along the way.

## M 392C (Bowen) Hyperbolic Geometry and Teichmüller Theory

**Description**

**Prerequisites:** Students are expected to be familiar with measure theory, L^p spaces and smooth manifolds. Otherwise, prerequisites will be kept to a minimum.

## M 392C (Allcock) Lie Groups

**Description**

**Material:**** **We will cover the basic theory of Lie Groups and Lie algebras, from the Lie correspondence through the classification theorem (over the complex numbers) and highest weight modules. If there is time, then I would also like to talk about Kazhdan's property (T), and/or the structure theory of real Lie groups and algebras. This structure theory tells you how to think about real Lie groups, but we will not be able to cover their classification. This theory is a prerequisite to understanding infinite-dimensional representations of Lie groups, but we will not be able to cover any of that, either.

**Prerequisites:** I will assume you are comfortable with the material from our first year graduate courses in topology and algebra. From topology, you absolutely need fluency with the fundamental group, covering spaces, and the language of differentiable manifolds. We will use deRham coholomogy a little bit, but you could get by with just a high-level understanding of it. From algebra you need fluency with group theory and multilinear algebra (including bilinear and Hermitian forms, and tensor products). No Galois theory will be needed, only a tiny bit of commutative algebra, and nothing with a ground field other than the real or complex numbers. From analysis we need only a little: enough to understand statements about Haar measure, and maybe what a Banach space is.

**Textbook:** notes prepared by me.

## M 393C (Maggi) Calculus of Variations on vector-valued maps

**Abstract:** Variational problems for energy functionals defined on classes of vector-valued maps arise in contexts of great geometric and physical interest (harmonic maps between manifolds, equilibrium problems in continuum mechanics, etc.). Several mathematical tools that are crucially important in the analysis of "scalar" variational problems are absent in the "vectorial" case (like, for example, the maximum principle), resulting in a long list of challenging (and still open) problems. In this course we will review both the general theory of vectorial variational problems and specific problems that well-illustrate the typical difficulties and expected results in this area.

This is an advanced graduate course, which requires familiarity with measure theory, functional analysis and other basic facts concerning Analysis and Partial Differential Equations.
