#### A new proof of Halasz theorem and pretentiousness in analytic number theory.

#### Mr. Pranendu Darbar

##### IMSc, Chennai

*In this talk, I will present a cheap proof of Halasz *

theorem and produce a distance function from it. Finally using this

distance function formulate the notion of pretentiousness between two

multiplicative functions and give some major application of it in

analytic number theory. This new approach is developed by Granville

and kannan soundararajan.
