OSAKA CENTRAL ADVANCED MATHEMATICAL INSTITUTE - DECEMBER 2025
Spectrums in Representation Theory of Algebras and Related Topics
Organizers :  Ryo Kanda · Kaveh Mousavand · Pablo S. Ocal
Description

The workshop will focus on the uses of the topological tools known as spectrum to understand the representation theory of algebras. This includes the Balmer, Cohn, Gabriel, Gelfand, maximal, Pierce, primitive, projective, punctured, triangulated, Zariski, and Ziegler spectrums, just to name a few. The workshop aims to provide a friendly introduction to some of these topic for newcomers, as well as to be a platform to discuss recent developments and interconnections.

The workshop is comprised of two minicourses, six invited talks, and several contributed talks. Junior researchers, postdoctoral scholars, and graduate students, are particularly encouraged to apply for contributed talks. We especially welcome applications from women and minority groups in mathematics.

The workshop will be held on

  • 16-19 December 2025,
  • Room E408,
  • Building E,
  • Faculty of Science,
