Dear all,

We are excited to begin after the summer break with a talk by Professor George Andrews, Atherton Professor of Mathematics, Penn State University.

Please note the unusual time for the seminar.

**Talk Announcement:**

**Title:**Extensions of MacMahon's Generalization of Sums of Divisors

**Speaker:**George Andrews (Penn State University)

**When:**Sept 19, 2024, 5:30 PM- 6:30 PM IST (8:00 AM EDT)

**Where**: Zoom: Write to the organisers for the link.

**Abstract:**

This talk is on joint work with Tewodros Amdeberhan and Roberto Tauraso. In our joint paper, Extensions of MacMahon’s Sums of Divisors (Research in the Math. Sciences, 11,8 (2024)), we examined the arithmetic properties of MacMahon’s original functions and their generalizations. In this talk, we consider further extensions of MacMahon’s work, and we look at both arithmetic and combinatorial aspects including a stunning identity for the generating function of the sum of the divisors of n.

Best wishes,

Gaurav Bhatnagar, Atul Dixit and Krishnan Rajkumar (organisers)
