AGENDA


Monday, March 24
  • Algebra Seminar, "Non-Noetherian Cohen-Macaulayness in Directed Unions of Power Series Rings". Richard Sayanagi, NMSU. 12:30PM – 1:30PM. SH 235 and Zoom Link: https://nmsu.zoom.us/j/89765494169.

Abstract: Power series rings over non-Noetherian rings can exhibit unexpected behavior, like possessing an infinite chain of prime ideals even when the base ring is local and 0-dimensional. We discuss a construction of directed unions of power series rings over non-Noetherian 0-dimensional rings that have properties seen in Noetherian Cohen-Macaulay rings, such as Krull's height theorem for finitely generated ideals and the unmixedness theorem. We make connections to several different notions of non-Noetherian Cohen-Macaulayness in the literature.

Abstract:  I’ll present on recent work extending a classification of principal actions on topological graphs to topological quivers, and dynamics on the associated operator algebras.
  • Colloquium, "Thermal Capacity and Hausdorff Dimension Results for Brownian Motion and Related Processes". Yimin Xiao, Michigan State University. 12:00PM refreshments | 12:30PM – 1:20PM. SH 107 and Zoom. Link: https://nmsu.zoom.us/j/82146375616.

Abstract: The A Priori Procedure (APP) aims to determine necessary sample sizes to ensure that sample statistics reliably estimate corresponding population parameters. As data collection in certain fields faces limitations and periodicity, the study of a priori confidence intervals that do not rely on actual data has become increasingly important. A priori confidence intervals enable researchers to identify a sample size 𝓃 such that the deviation and corresponding probability between the sample statistic and the population parameter fall within a specified range. This approach allows researchers to plan sample sizes before data collection, enhancing the reliability and efficiency of their research. This talk will focus on deriving APP equations for determining required sample sizes and constructing confidence intervals for parameters within the family of skewnormal distributions. Applications using real data sets will be presented to illustrate the main results.
  • Geometry and Topology Seminar, "TBA". Ross Staffeldt, NMSU. 2:00PM – 3:00PM. Zoom and SH 107. Link: https://nmsu.zoom.us/j/96482605257.
Abstract: TBA
