Auburn Algebra Seminar
Fall 2025
Schedules from past semestersSeminars will be held in Parker 354 on Tuesdays from 2:30 to 3:20, unless otherwise noted.
Schedule:
August 25 (Monday): Hoa Dinh (Troy University). Note the unusual day!Title: Quantum algorithms for Kubo-Ando means
Abstract: In this talk, we discuss the construction of a quantum algorithm for computing Kubo–Ando means. We also show how similar techniques can be extended to Bures means, weighted spectral geometric means, power means, and other related matrix means.)
August 26: Ming-Cheng Tsai (National Sun Yat-sen University)
Title: Multiplicative spectrum and trace preservers on complex and stochastic matrices
Abstract: In this talk, we mainly explore multiplicative spectrum and trace preservers on the set of complex and stochastic matrices. We will give concrete description of spectrum and trace preservers on the sets of complex matrices, doubly stochastic, row stochastic, and column stochastic, respectively. Some related examples and results are provided.

Title: m-adic Continuity of Frobenius Splitting Ratio
Abstract: The study of singularities under perturbation is classical, with origins dating back to the 50's and 60's through the work of Samuel and Hironaka. In this talk, we introduce the theory of F-singularities in prime characteristic rings and examine continuity problems in relation to perturbation theory. Our main result characterizes the continuity of the F-splitting ratio.
