Modular forms for noncongruence subgroups: recent progress and open problems Modular forms for congruence subgroups have been studied for over one century. There are fabulous results and remarkable applications. On the other hand, the arithmetic of modular forms for noncongruence…

An introduction to the principle of functoriality I will give a brief introduction to the principle of functoriality, which is one of the central components of the Langlands program. Then we will go over a few examples of the principle…

Level of Siegel modular forms of degree 2 coming from the $latex Sym^3$ lifting Ramakrishnan and Shahidi used the $latex Sym^3$ lifting to lift a holomorphic elliptic (non-CM) newform $latex f$ of weight $latex 2k$ and level $latex N$ to…

The tensor-like join: graph-theoretic insights into polar code performance Arikan's polar codes have been celebrated for their capacity-achieving performance since first presented in 2008; however, the question of optimal finite-length design and decoding remains open. To understand the efficacy of…

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…
