Title: Lower bounds on Weil height for certain infinite non-Galois extensions
Abstract: For a non-zero algebraic number $\alpha$, let $h(\alpha)$ denote its logarithmic Weil height. A classical theorem of Kronecker asserts that $h(\alpha)=0$ if and only if $\alpha$ is a root of unity. For $\alpha$ not a root of unity, it is an important theme to understand lower bounds for $h(\alpha)$. In 2002, Bombieri and Zannier obtained explicit lower bounds on certain infinite Galois extensions in terms of their local degrees. In this talk, we formulate and prove an analogous result for infinite non-Galois extensions. This is joint work with Sushant Kala.

Title: On the zeros of variants of Ramanujan polynomials
Abstract: In 2011, M. R. Murty, C. Smyth and R. Wang introduced the family of 'Ramanujan polynomials' and proved that the non-real zeros of all such polynomials lie on the unit circle. These polynomials are related to the period polynomial of standard Eisenstein series. Since then, it has been established that period polynomials associated to generalized Eisenstein series and Hecke newforms also have all their roots on the unit circle. In this talk, we discuss recent results regarding the unimodularity of zeros of certain cognate polynomials.

Title: The distribution of k-full numbers
Abstract: A positive integer n is called k-full if for each prime divisor p of n, p^k divides n. We will explore some questions related to the distribution of k-full numbers and some variations on these questions.
