PIMS CRG Seminar Series: L-functions in Analytic Number Theory: Pranendu Darbar

  • Date: 10/06/2022
Speaker(s):
Pranendu DarbarNorwegian University of Science and Technology
Location: 

Hybrid

Topic: 

Multiplicative functions in short intervals

Description: 

In this talk, we are interested in a general class of multiplicative functions. For a function that belongs to this class, we will relate its “short average” to its “long average”. More precisely, we will compute the variance of such a function over short intervals by using Fourier analysis and by counting rational points on certain binary forms. The discussion is applicable to some interesting multiplicative functions such as

 

μk(n), φ(n)/n, n/φ(n), μ2(n) φ(n)/n, σα(n), (−1)#{p : p k|n}(n),

 

and many others and it provides various new results and improvements to the previous result
in the literature. This is a joint work with Mithun Kumar Das.

 

This event is part of the PIMS CRG Group on L-Functions in Analytic Number Theory. More details can be found on the webpage here: https://sites.google.com/view/crgl-functions/crg-weekly-seminar
