Noise Sensitivity Governed by Continuous-Time Random Walks on the Symmetric Group

Gideon Amir, Subhajit Ghosh

We study the noise sensitivity of Boolean functions on the symmetric group $S_{n}$ , where noise is induced by running a continuous-time Markov chain on $S_{n}$ . We investigate the nois…

Asymptotics of the Number of Components of Random Polynomial Lemniscates

Subhajit Ghosh, Koushik Ramachandran, Atul Shekhar

Consider a sequence of random polynomials $P_{n} (z) = \prod_{k = 1}^{n} (z - X_{k})$ , where ${X_{k}}_{k}$ are i.i.d. random variables distributed uniformly on the unit disc $D$ . Le…

A note on the Erdös minimal area problem

Subhajit Ghosh, Koushik Ramachandran

We answer a question of Erdős, Herzog, and Piranian \cite[Problem $4$ , page $135$ ]{EHP} on the minimal area of polynomial lemniscates when all the zeros of the polynomial are const…

Constraining ALP-Meson overlaps from $K π$ form factors

Triparno Bandyopadhyay, Subhajit Ghosh

We present the first constraints on the overlaps between an Axion-like particle (ALP) and the $π^{0}$ and $η$ mesons from the analysis of the distortions to the $\langle K|\overline{…

Spectral gap for the signed interchange process with arbitrary sets

Gil Alon, Subhajit Ghosh

In 2020, F. Cesi introduced a random walk on the hyperoctahedral group $B_{n}$ and analysed its spectral gap when the allowed generators are transpositions and diagonal elements corr…

Mixability of finite groups

Gideon Amir, Guy Blachar, Subhajit Ghosh +1

Say that a finite group $G$ is mixable if a product of random elements, each chosen independently from two options, can distribute uniformly on $G$ . We present conditions and obstr…

Limit profile for the transpose top-2 with random shuffle

Subhajit Ghosh, Nishu Kumari

The transpose top- $2$ with random shuffle (J. Theoret. Probab., 2020) is a lazy random walk on the alternating group $A_{n}$ generated by $3$ -cycles of the form $(⋆, n - 1, n)$ and $…

Number of components of polynomial lemniscates: a problem of Erdös, Herzog, and Piranian

Subhajit Ghosh, Koushik Ramachandran

Let $K \subset C$ be a compact set in the plane whose logarithmic capacity $c (K)$ is strictly positive. Let $P_{n} (K)$ be the space of monic polynomials of degree $n…
