Abstract
In this two-part talk, we will show first that the notion of locality in codes has a very natural extension to codes with hierarchical locality. We provide a bound on the minimum distance of such codes as well as two general constructions that achieve this bound. The second part of the talk will describe a recent construction of an MSR regenerating code with polynomial sub-packetization level. This is joint work with Birenjith Sasidharan and Gaurav Agarwal.
