KUMUNU 2021 (now occurring in May 2022)


January, 2022: KUMUNU will be held May 7-8, 2022.


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 conference will begin at 1 p.m. on Saturday, May 7, 2022, and conclude around noon on Sunday, May 8.
  • To be held in-person in Avery Hall on the campus of the University of Nebraska–Lincoln, masks may be required depending on local health conditions.
  • Featuring research talks from prominent mathematicians working outside of the region and new results of researchers from regional institutions.
  • Poster session for junior researchers.
  • Reception on Saturday night.
  • We are aware of an email scam regarding 'Accommodations in Lincoln' asking you to book a hotel for KUMUNU. Please ignore this and instead follow the instructions for booking a hotel room at the Graduate Hotel that are given on the conference registration form.
