Speaker: Francois Seguin

Title: The complementary two-variable problem.

Abstract: In light of our previous talks concerning the two-variable Artin conjecture, one could ask about a "reverse" or "complementary" analogue. During this talk, we will describe this analogue as well as present a proof due to Schinzel from 1960. We will then discuss how much the proof can be modified to obtain a more precise result.

Strength in Numbers: A Graduate Workshop in Number Theory and Related Areas

Dates: Friday, May 11th and Saturday, May 12th, 2018

Venue: Jeffery Hall, Queen's University

This is a two-day workshop aimed primarily at graduate students. Participation is open to all. There are five plenary talks by experts and many contributed talks by graduate students on a topic of their choice. Schedules and abstracts of the talks are attached with this email.

A novel feature of this workshop is a presentation by Prof. Erin Maloney, a psychologist specializing in math anxiety and related areas. The invited speakers will also lead a panel discussion regarding professional development on Saturday. Questions can be submitted here - https://docs.google.com/forms/d/e/1FAIpQLSdedZpevw4t8mDHlctq1Nmbmz3hX6v6IC-pyeBmV79jlWLM2g/viewform?usp=sf_link

Time: 4:00-5:30p.m.  Place: Jeffery Hall 422

Speaker: M. Ram Murty (Queen's University)

Title: SPECIAL VALUES OF MODULAR $L$-SERIES.

Abstract: We will discuss the Rankin-Selberg method as well as the analytic continuation of Eisenstein series that allows us to evaluate special values of modular $L$-series at critical point (in the sense of Deligne).

Speaker: Siddhi Pathak (Queen's University)

Title: On the primitivity of Dirichlet characters.

Abstract: A Dirichlet character modulo q is said to be imprimitive if it is induced from a lower level. A characterization of the primitivity of characters is the separability of the Gauss sum ( Fourier transform of $\chi$ ), i.e., $G_q(n, \bar{chi}) = \chi(n) G_q(1, \bar{ \chi } )$ for all n. In this talk, we discuss a paper of R. Daielda and N. Jones in which they introduce another way of extending primitive Dirichlet characters so that the above separability property holds even for imprimitive characters.

Speaker: Arpita Kar (Queen's University)

Title: On the normal number of prime factors of Ramanujan Tau function.

Abstract: We will discuss various results concerning $\omega(\tau(p))$, $omega(\tau(n))$, $\omega(\tau(p+1))$ where $\tau$ denotes Ramanujan Tau function and $\omega(n)$ denotes the number of prime factors of $n$ counted without multiplicity. This is work in progress with Prof. Ram Murty.
