### Catherine Hsu – University of Oregon

Higher Eisenstein Congruences In this talk, we examine the relationship between the ``depth" of certain Eisenstein congruences and the local structure of the Eisenstein ideal. Specifically, let $latex p\geq 3$ be prime. For squarefree level $latex N>6$ and weight $latex…

On Ferrers Diagram Codes Rank-metric codes play a crucial role in the area of random network coding. Mathematically, they are subspaces of a matrix space $latex \mathbb{F}^{m\times n}$ over a finite field $latex \mathbb{F}$, and where the matrix space is…

Coding Techniques for Partial Erasure Channels. Partial erasure channels were recently introduced to model erasure events in applications such as flash memories. In these channels, some information may remain after an erasure event. After reviewing these channels, we present results…

Efficient computations of bilinear pairings on elliptic curves over finite fields. The Tate and Weil pairings play a vital role in computational number theory. For example, the Weil pairing can be used to determine the group structure of an elliptic…

Distributed Storage Erasure codes, originally designed to provide reliability against noise on communication channels, are now widely used in distributed storage systems. Distributed storage systems require the codes to have new properties such as low-cost repair of failed nodes, high…

Coded Computing Large-scale distribute computing frameworks such as MapReduce and Spark employ massive parallelization of jobs. While parallelism drastically reduces computation time, slow or straggling nodes can become a bottleneck in job completion. In this talk, we will study erasure codes for…

Rateless Codes Rateless fountain codes are a class of erasure codes where the source generates an unlimited stream of symbols until the data is recovered at the receiver. This rateless property makes them well-suited for many applications including multicast communication, distributed…
