L-functions in Analytic Number Theory: Jackie Voros

The least quadratic non-residue has been a central problem in number theory for centuries. The average least quadratic non-residue was explored by Erdős in the 1960s, and many extensions of this problem such as to the average least character non...

Lethbridge Number Theory and Combinatorics Seminar: Fatma Cicek

In this talk, we will study the first and second twisted moments of some Rankin-Selberg convolution L-functions of an automorphic form of prime power level. Our first moment result can be used to prove that automorphic forms of suitable weight and...

L-functions in Analytic Number Theory: Henry Twiss

Subconvexity problems have maintained extreme interest in analytic number theory for decades. Critical barriers such as the convexity, Burgess, and Weyl bounds hold particular interest because one usually needs to drastically adjust the analytic...

L-functions in Analytic Number Theory: Martin Čech

There are two ways to compute moments in families of L-functions: one uses the approximation by Dirichlet polynomials, and the other is based on multiple Dirichlet series. We will introduce the two methods to study the family of real Dirichlet L...

Lethbridge Number Theory and Combinatorics Seminar: Alice Lacaze-Masmonteil

A directed variant of the famous Oberwolfach problem, the directed Oberwolfach problem considers the following scenario. Given n people seated at t round tables of size m1,m2…,mt, respectively, such that m1+m2+⋯+mt=n, does there exist a set of n−1...

L-functions in Analytic Number Theory: Saloni Sinha

We study sums of the form ∑n≤x f(n) n⁻ⁱʸ, where f is an arithmetic function, and we establish an equivalence between the Riemann Hypothesis and estimates on these sums. In this talk, we will explore examples of such sums with specific arithmetic...

L-functions in Analytic Number Theory: Christine K. Chang

We will present a matching upper and lower bound for the right tail probability of the maximum of a random model of the Riemann zeta function over short intervals. In particular, we show that the right tail interpolates between that of log-correlated...

Lethbridge Number Theory and Combinatorics Seminar: Emily Quesada Herrera

In 1973, assuming the Riemann hypothesis (RH), Montgomery studied the vertical distribution of zeta zeros, and conjectured that they behave like the eigenvalues of some random matrices. We will discuss some models for zeta zeros � starting from the...

L-functions in Analytic Number Theory: Andrés Chirre

In this talk, we will discuss a well-known formula of Ramanujan and its relationship with the partial sums of the Möbius function. Under some conjectures, we analyze a finer structure of the involved terms. It is a joint work with Steven M. Gonek...

Lethbridge Number Theory and Combinatorics Seminar: Hermie Monterde

Let G be a graph with adjacency matrix A. A continuous quantum walk on G is determined by the complex unitary matrix U(t)=exp(itA), where i2=−1 and t is a real number. Here, G represents a quantum spin network, and its vertices and edges represent...

L-functions in Analytic Number Theory: Greg Knapp

In 1909, Thue proved that when $F(x,y)$ is an irreducible, homogeneous, polynomial with integer coefficients and degree at least 3, the inequality $\left\| F(x,y) \right\| \leq h$ has finitely many integer-pair solutions for any positive $h$. Because...
