Fall 2023 Courses
Restrictions
Several undergraduate and graduate courses contain restrictions during the regular registration period, to ensure that students who have completed the registration requirements will have the best chance at successfully registering for their preferred courses. Some of these restrictions will be lifted later in the registration period.
 MATH 347: Major restrictions will be removed during business hours (8:30 a.m. or later) on April 20, 2023. Some seats are reserved for incoming students in programs requiring this course. Any remaining seats would be released on the Friday before fall classes begin. For information about the Honors section of MATH 347, see "Honors Courses" in the following section.

Honors Courses
The department offers the three following honors mathematics courses to undergraduate students:
 Honors MATH 347
 Honors MATH 416
 MATH 425
Students interested in taking mathematics honors courses should have A grades in prior coursework and must obtain approval from the undergraduate advising team to register for honors courses. To express interest in registering for these courses, email mathadvising@illinois.edu using the subject line “Honors course request: [347/416/425]” (please specify which course you'd like to take). In the same email, include your name, UIN, netID, the reason for your interest, and your qualifications for applying to the honors course.
Honors Section of Math 347
Enrollment in this honors section is restricted to students who have shown excellence in mathematics. Completion of Math 241 is typically expected as well. To request permission for this section please email mathadvising@illinois.edu with name, UIN, and reason for interest. Students who have demonstrated excellence in mathematics may use this section for James Scholar credit, but the section is not restricted to James Scholars.
Undergraduate Topics Courses
Course offerings in undergraduatelevel mathematics topics are as follows:
 MATH 199, Conversations in Mathematics (Undergraduate Open Seminar)
This course is for those who wish to experience mathematics through experimentation, reflection, intuition, and conversation. We will explore a number of provocative, interesting, and important ideas from the canon of mathematics. The goal of this course is to offer the student memorable, lifelong topics of conversations about math. Assessment will be through evaluation of student journal entries. For Chancellor's Scholars only; other may only enroll with the consent of the instructor and the Campus Honors Program.
 MATH 428, Honors Topics: Introduction to Fourier Analysis
Fourier analysis is one of the most influential fields in mathematics with applications in analysis, differential equations, number theory, geometry, quantum mechanics, signal processing and many others. This is an introductory course to Fourier analysis. It will focus on rigorous development of basic concepts in the area. Prerequisites are MATH 447 or equivalent such as MATH 424 or MATH 444. This course will also require some familiarity with complex numbers and basic linear algebra. Topics to be covered include:

Fourier series solutions of wave and heat equations

Properties of Fourier series: decay of coeffcients, uniqueness, convergence, summability

Fourier series of square integrable functions; Vector spaces and inner products; Parseval's and Placherel identities.

Some applications of Fourier series: Isoperimetric inequality, Weyl's equidistribution theorem

Fourier transform on R. Schwartz space. Fourier inversion. Poisson summation formula. Uncertainty principle

Further topics (if time permits): Fourier transform on Rd. Radial symmetry and Bessel functions. Xray and Radon transforms


MATH 490, Quantum Information Theory
The goal of this course is to provide a rigorous introduction to the mathematical aspects of quantum information theory. The second postulate of quantum mechanics states that the dynamics of any closed (isolated) quantum system is determined by unitary evolution. Though, in reality, every system is open! And thus, there is always some interaction with an external system (the environment). Thus, disturbance of the state of our initial system is an occurrence which we must get used to and learn how to work with. Quantum channels may be defined via such processes. In particular, a quantum channel is a completely positive trace preserving map which changes the state of your system. The focus of the first half of term will be to study quantum channels and their properties. This includes the study of subclasses of quantum channels and unital channels, and various representation theorems for quantum channels. The next task will be to look at similarity and distance amongst states and channels. This includes quantum state and channel discrimination, the fidelity function, distance between quantum channels, and majorization. The focus of the second half of term will be on quantum error correction. Classical error correction is a very well understood, and welldeveloped field. For many years it was unknown if quantum error correction was possible. Three major hurdles are present when moving from classical error correction, to quantum error correction: in short 1) (quantum) errors are continuous 2) the nocloning theorem 3) measurements destroy quantum information. Despite this, after the seminal work of Shor, Steane and others, exciting progress in the area of quantum error correction is happening every day! During this second half of term, we will learn the basics and touch on some important/foundational aspects of the theory. Such topics include Shor’s 9 qubit code, the stablilizer formalism, and the KnillLaflamme subspace condition. Prerequisite: MATH 416 or equivalent proofbased linear algebra. No prior knowledge of quantum physics is expected.

Special Course Requests
Graduate Students May Request to Take a 400Level Course for 4 Credits
Many 400level MATH classes are offered as 3credit sections by default, but some may have a 4credit option available to graduate students, at the instructor’s discretion. Please note that the inclusion of a 4credit section on the timetable does not guarantee that the instructor will be offering a 4credit option.
Graduate students requesting the 4 credit hour section must first register for the 3 hour section. If the instructor is willing to offer extra work to graduate students for the 4hour section, students can fill out the request form between the first day of the semester and the 8th week of the semester at this link: https://go.math.illinois.edu/3to4credit
Undergraduate Students May Request to Take a 500Level Course
Undergraduate students who are interested in taking a graduate mathematics course should first have completed significant work at the 400level with A or A+ grades. To request approval to take a graduate MATH course, please email mathundergraddirector@illinois.edu using the subject line “Undergraduate requesting a graduate course.” The same email should include your name, netID, UIN, the course you're requesting to take, the CRN of the course requested, and reason for your request.
Note that for some classes, including MATH 500 and MATH 540, review may be delayed to ensure that students in mathematics graduate programs are able to register for the classes they need. Review may also be delayed if the current semester’s class grades are needed for the review.
