2022-2023 Colloquia

Title: Research in the theory of core partitions
Speaker: Dr. Rishi Nath (York College The City University of New York)
Date: Wednesday, November 9, 2022
Time: 12:30pm - 1:30pm
Room: S-213 (Dr. Joseph Bertorelli Classroom)


Partitions and their hook sets are a relatively accessible area of mathematical study which is deeply important to both number theory and representation theory. Come learn what a core partition is, what questions people have about them, and about research opportunities for undergraduates in this area.

Speaker: Dr. Bianca Sosnovski (Queensborough Community College)
Date: Wednesday, October 12, 2022
Time: 12:30pm - 1:30pm
Room: S-213 (Dr. Joseph Bertorelli Classroom)


In this talk we present a connection between semi-primitive roots of the multiplicative group of integers modulo 2k where k _ 3 and the logarithmic base in the algorithm introduced in 2004 by Fit-Florea and Matula for computing the discrete logarithm modulo 2k. We will show that their results can be extended to any semi-primitive root modulo 2k and present a generalized version of their algorithm to find the discrete logarithm modulo 2k.

Title: Clebsch-Gordan coefficients for anti-magic squares
Speaker: Dr. Robert Donley (Queensborough Community College)
Date: Wednesday, September 21, 2022
Time: 12:30pm - 1:30pm
Room: S-213 (Dr. Joseph Bertorelli Classroom)


Clebsch-Gordan coefficients play an important role in the quantum theory of angular momentum.  A central feature of the theory is the poset of semi-magic squares of size three, which suggests generalizations of a combinatorial nature.  We consider the difficulties for semi-magic squares of larger size, including a digression on Latin square enumeration.  Then we describe a theory of Clebsch-Gordan coefficients for so-called anti-magic squares that retains most of the combinatorial features.  Parts of this work are joint with WonGeun Kim and the RAMMP Summer 2022 REU.
