# On Cilleruelo's conjecture for the least common multiple of polynomial sequences

## TL;DR

This paper investigates Cilleruelo's conjecture on the asymptotic growth of the least common multiple of polynomial sequences, proving a version of the conjecture for most shifts of a fixed polynomial.

## Contribution

It establishes a near-universal version of Cilleruelo's conjecture for almost all shifts of a fixed polynomial, expanding understanding of LCM growth in polynomial sequences.

## Key findings

- Proves the conjecture for almost all shifts of a polynomial.
- Shows the growth rate of LCM aligns with the conjectured asymptotic.
- Extends previous results to a broader class of polynomial shifts.

## Abstract

A conjecture due to Cilleruelo states that for an irreducible polynomial $f$ with integer coefficients of degree $d\geq 2$, the least common multiple $L_f(N)$ of the sequence $f(1), f(2), \dots, f(N)$ has asymptotic growth $\log L_f(N)\sim (d-1)N\log N$ as $N\to \infty$. We establish a version of this conjecture for almost all shifts of a fixed polynomial, the range of $N$ depending on the range of shifts.
