Repdigits as Product of Consecutive Shifted Tribonacci Numbers
Pranabesh Das, Salah Eddine Rihane, Alain Togbé
A repdigit is a positive integer that has only one distinct digit in its decimal expansion, i.e., a number has the form for some and . Let…
Continuous-Time Modelling of Black Hole Binary Evolution with Neural ODEs
Julian Chan, Alessia Gualandris, Payel Das
Pulsar timing arrays (PTAs) can detect the low-frequency stochastic gravitational-wave background (GWB) generated by an ensemble of supermassive black hole binaries (BHBs). Accurat…
Gamma Hedging without Rough Paths
John Armstrong, Purba Das
We show how the robustness of gamma hedging can be understood without using rough-path theory. Instead, we use the concepts of variation along a partition sequence and Tay…
Noise estimation of SDE from a single data trajectory
Munawar Ali, Purba Das, Qi Feng +2
In this paper, we propose a data-driven framework for model discovery of stochastic differential equations (SDEs) from a single trajectory, without requiring the ergodicity or stat…
Products of Tribonacci Numbers that are the Products of Factorials
Pranabesh Das, J. C. Saunders
In 2014 Marques and Lengyel gave all of the solutions to the equation , where is the th term of the Tribonacci sequence . In 2023 Alahmad…
On the convexity of Berezin range and Berezin radius inequalities via a class of semi-norms
Athul Augustine, P. Hiran Das, Pintu Bhunia +1
This paper introduces a new family of semi-norms, say -Berezin norm on the space of all bounded linear operators defined on a reproducing kernel Hilbert spa…
