Title: Rational points on modular abelian surfaces and special values of p-adic L-functions
 
Abstract: In this talk I will present  work in progress with M. Bertolini, M. Seveso and R. Venerucci relating rational points on modular abelian surfaces, of $GL_2$ type  over $Q$, and special values of suitable $p$-adic $L$-functions. Most of the talk will be devoted to the definition of the latter.

Title: Primes of the form x²+dy² and interactions of class groups

Abstract: The form x²+y² covers ½ of the primes, while the forms x²+y², x²+2y² cover ¾ of them. In this talk, we will show that the proportion of primes covered by the forms x²+dy², 1 ≤ d ≤ Δ, is

1 - exp((α(Δ) + o(1)) √Δ / log Δ)

for some 7π/12 ≤ α(Δ) ≤ 7π/12 + log 4. Furthermore, inspired by a result of Kaplansky, we prove that any prime covered by two of the forms

x²+17y², x²+65y², x²+1105y²

Title: Artificially Intelligent Geospatial Systems: A Case Study in Energetics for Mobile Health Data.

This workshop will provide an overview of the different types of market research, how to analyze the competition, and the resources available at McGill to perform market research. Our market research librarian will walk us through some of those resources using a new market research canvas tool.
