KUMUNU, which is named for its original participating institutions (the University of Kansas, the University of Missouri–Columbia, and the University of Nebraska–Lincoln), has been an annual conference for commutative algebraists in the Great Plains region since 1999. It has grown significantly since its inception, and currently attracts about 100 participants from a significantly larger geographical region. The goal of KUMUNU is to provide a setting to share cutting-edge mathematical research and promote collaborations among algebraists in or within driving distance of the Great Plains region. Major goals specific to KUMUNU are to broaden the geographic reach of the conference, promote connection between commutative algebra and related areas, and showcase the research of early career mathematicians. The University of Nebraska–Lincoln is hosting KUMUNU in the falls of 2019, 2020, and 2021.

  • Sept. 21-22, 2019
  • University of Nebraska–Lincoln
  • Research talks from prominent mathematicians working outside of the region and new results of researchers from regional institutions
  • Poster session for junior researchers
  • Dinner and reception

Contact conference coordinator Marilyn Johnson to participate in the conference and/or ask any questions.

Graduate Hotel Lincoln

To register for the conference please fill out the registration form. Most conference participants will be staying at the Graduate Hotel at 9th and O Streets. However, the deadline for having the conference reserve rooms at this hotel has passed. We expect to have some funds available to offset transportation costs. Priority for these funds will be for graduate students and postdocs and for those sharing transportation. Reimbursement forms for transportation costs will be available at the registration desk.

Parking and Meeting Information

A campus parking map can be found here.


  • If you are staying at the Graduate Hotel and arrive early enough you can park your car in the Graduate hotel parking garage. (The cost will be added to your hotel bill and direct-billed to the Department.) It is then a 10-15 minute walk to Burnett Hall.
  • For on campus parking, there are some 50 metered parking stalls located in the parking lot west of Avery Hall and south of the stadium. (The lot is labelled F4/D2 on the campus map.) The meters are free after 12pm on Saturday and all day on Sunday. However, these stalls tend to fill up quickly.
  • Another on campus option is to park in the Stadium Drive parking garage just west of the stadium and the metered lot mentioned above. The cost is hourly ($1 per hour, I think) with a maximum of $7 per day.


  • If you are staying at the Graduate, you can leave your car in the hotel parking garage (even if you check out) and walk to Burnett Hall.
  • You can park in the metered spots in the lot west of Avery (free all day). You can also park in the metered spots on Stadium Drive, which are also free on Sunday.

All talks will be held in Burnett Hall 115 on the campus of the University of Nebraska-Lincoln. For those of you familiar with our department, Burnett Hall is the building immediately east of Avery Hall, where the math department is located. A campus map can be found here.
