On the distribution of Alexander polynomials in certain families of closed braids

Anwesh Ray

We study the distribution of arithmetic invariants associated to Alexander polynomials for certain infinite families of links. The families of links we consider arise from braids o…

On the number of subrings of $Z^{n}$ of prime power index

Hrishabh Mishra, Anwesh Ray

Let $n$ and $k$ be positive integers, and $f_{n} (k)$ (resp. $g_{n} (k)$ ) be the number of unital subrings (resp. unital irreducible subrings) of $Z^{n}$ of index $k$ . The numbers…

Galois representations ramified at one prime and with suitably large image

Anwesh Ray

Let $p \geq 7$ be a prime and $n > 1$ be a natural number. We show that there exist infinitely many Galois representations $\varrho:Gal(\bar{\mathbb{Q}}/\mathbb{Q})\rightarrow GL_{n}(…

An analogue of Kida's formula in graph theory

Anwesh Ray, Daniel Vallières

Let $ℓ$ be a rational prime and let $p : Y \to X$ be a Galois cover of finite graphs whose Galois group is a finite $ℓ$ -group. Consider a $Z_{ℓ}$ -tower above…

A note on the distribution of Iwasawa invariants of imaginary quadratic fields

Anwesh Ray

Given an odd prime number $p$ and an imaginary quadratic field $K$ , we establish a relationship between the $p$ -rank of the class group of $K$ , and the classical $λ$ -invariant of t…

Diophantine equations of the form $Y^{n} = f (X)$ over function fields

Anwesh Ray

Let $ℓ$ and $p$ be (not necessarily distinct) prime numbers and $F$ be a global function field of characteristic $ℓ$ with field of constants $κ$ . Assume that there exists a p…

Remarks on Hilbert's tenth problem and the Iwasawa theory of elliptic curves

Anwesh Ray

Let $E$ be an elliptic curve with positive rank over a number field $K$ and let $p$ be an odd prime number. Let $K_{cy c}$ be the cyclotomic $Z_{p}$ -extension of $K$ and $K_n…

On the distribution of Iwasawa invariants associated to multigraphs

Cédric Dion, Antonio Lei, Anwesh Ray +1

Let $ℓ$ be a prime number. The Iwasawa theory of multigraphs is the systematic study of growth patterns in the number of spanning trees in abelian $ℓ$ -towers of multigraphs.…

Asymptotic growth of Iwasawa invariants in Noncommutative towers of number fields

Anwesh Ray

Let $p$ be an odd prime, $F$ be a number field and consider a uniform infinite pro- $p$ extension $F_{\infty}$ of $F$ with Galois group $G = G a l (F_{\infty} / F)$ . Let \[G=G_0\supset G_1\sup…

Class group statistics for torsion fields generated by elliptic curves

Anwesh Ray, Tom Weston

For a prime $p$ and a rational elliptic curve $E_{/ Q}$ , set $K = Q (E [p])$ to denote the torsion field generated by $E [p] := ker {E p E}$ .…

Topological Iwasawa invariants and Arithmetic Statistics

Cedric Dion, Anwesh Ray

Given a prime number $p$ , we study topological analogues of Iwasawa invariants associated to $Z_{p}$ -covers of the $3$ -sphere that are branched along a link. We prove explic…

On the $μ$ equals zero conjecture for the fine Selmer group in Iwasawa theory

Shaunak V. Deo, Anwesh Ray, R. Sujatha

We study the Iwasawa theory of the fine Selmer group associated to certain Galois representations. The vanishing of the $μ$ -invariant is shown to follow in some cases from a natura…
