Co-Addition for free Non-Associative Algebras and the Hausdorff Series [PDF]

open access: yesJ. Algebra 265 (2003), no. 1, 264--284., 2002
Generalizations of the series exp and log to noncommutative non-associative and other types of algebras were considered by M.Lazard, and recently by V.Drensky and L.Gerritzen. There is a unique power series exp(x) in one non-associative variable x such that exp(x)exp(x)=exp(2x), exp'(0)=1.

Davenport's constant for groups with large exponent [PDF]

open access: yesContemporary Mathematics 579 (2012), 21-32, 2017
Let $G$ be a finite abelian group. We show that its Davenport constant $D(G)$ satisfies $D(G)\leq \exp(G)+\frac{|G|}{\exp(G)}-1$, provided that $\exp(G)\geq\sqrt{|G|}$, and $D(G)\leq 2\sqrt{|G|}-1$, if $\exp(G)<\sqrt{|G|}$. This proves a conjecture by Balasubramanian and the first named author.
