Our next speaker is Murali Srinivasan of IIT Bombay (at Mumbai). The talk announcement is below.

Talk Announcement:

Title: A q-analog of the adjacency matrix of the n-cube.

Speaker: Murali K Srinivasan (IIT Bombay)
When: Thursday, May 5, 2022 - 4:00 PM - 5:00 PM (IST) 

Where: Zoom

Tea or Coffee: Please bring your own.


Random walk on the $n$-cube gives rise to two matrices, the adjacency matrix and the Kac matrix, that have an elegant spectral theory with many applications.

We define a random walk on subspaces that yields q-analogs of the adjacency and Kac matrices with an equally elegant spectral theory (though more difficult to prove). We give an application to tree counting.

This is joint work with Subhajit Ghosh.
