|Brief course description: We will cover the majority of the Atiyah-MacDonald textbook. The textbook is a terse introduction to commutative algebra, so some extra material included in the exercises or from the Eisenbud textbook will also be presented. This is a first course in commutative algebra, which assumes some basic concepts from ring theory are already known. Topics covered include commutative rings, ideals, modules, localization, primary decomposition, integral extensions, Noetherian rings, the Nullstellensatz, Artinian rings, DVRs and Dedekind domains, completions, and dimension theory. A secondary goal of the course is an introduction to the dictionary between commutative algebra and algebraic geometry; many of these connections will be further explored in exercises.|
|Prerequisites: Math 536, Abstract Algebra. While at the surface most of our treatment will be self-contained, previous encounters with rings and modules are likely essential to keep up in the course. The "middle chapters" of Dummit and Foote "Abstract Algebra" are a good reference for any lacking background.|
|Course Delivery: The course will be presented online via Zoom in a remote synchronous mode. Students are strongly encouraged to both ask and answer questions, and due to the relatively small size of the class it is encouraged to share cameras. The instructor will record lecture notes on a tablet device and post the notes from class each day. Recordings of lectures will also be posted after class, but in-class attendance is strongly encouraged whenever feasible. You and other students will and *should* have many questions to be answered, and you should always feel free to interrupt when something is not clear. If you have a question, many of your fellow students probably have the same question, and we can save a great deal of time and confusion by addressing it.|
There will be approximately 7 problem sets, due at the beginning of class every other Wednesday. Homework sets will be long, since it is intended that a student who completes all the exercises will be ready to use the material in further courses and research. I strongly encourage all students to complete the homework, especially if commutative algebra is likely to be relevant to your eventual research specialty. This material is challenging, and it is not possible to learn the subject "by osmosis." However, I understand that you have many competing demands on your time (especially as you progress in your Ph.D. studies). You are all adults, so you may determine your own goals for the course and complete the homework accordingly.
|Grading and Expectations: Your grade will be based on a combination of your homework and attendance.|
|Academic Integrity Statement: Academic integrity is the pursuit of scholarly activity in an open, honest and responsible manner. Academic integrity is a basic guiding principle for all academic activity at The Pennsylvania State University, and all members of the University community are expected to act in accordance with this principle. Consistent with this expectation, the University’s Code of Conduct states that all students should act with personal integrity, respect other students’ dignity, rights and property, and help create and maintain an environment in which all can succeed through the fruits of their efforts. Academic integrity includes a commitment by all members of the University community not to engage in or tolerate acts of falsification, misrepresentation or deception. Such acts of dishonesty violate the fundamental ethical principles of the University community and compromise the worth of work completed by others.|
Disability Statement: Penn State welcomes students with disabilities into the University’s educational programs. Every Penn State campus has an office for students with disabilities. Student Disability Resources (SDR) website provides contact information for every Penn State campus. For further information, please visit the Student Disability Resources website.|
In order to receive consideration for reasonable accommodations, you must contact the appropriate disability services office at the campus where you are officially enrolled, participate in an intake interview, and provide documentation. See documentation guidelines. If the documentation supports your request for reasonable accommodations, your campus disability services office will provide you with an accommodation letter. Please share this letter with your instructors and discuss the accommodations with them as early as possible. You must follow this process for every semester that you request accommodations.
