**Title:** On a modification of Griffiths' method

**Speaker:**Eshita Mazumdar, Harish-Chandra Research Institute, Allahabad

**Abstract:** For a finite abelian group G with exp(G) = n, and a non-empty
set A ; [1, n - 1] arithmetical invariant s_A(G) is defined to
be the least integer k such that any sequence S with length k of elements
in G has a A-weighted zero-sum subsequence of length n. When A = {1}, it
is the Erdos-Ginzburg-Ziv constant and is denoted by s(G). In my
talk I would like to present modification of a method of Griffiths ([1])
over a cyclic group $ \mathbb{Z}_n $. It has been observed by doing that we are able to
provide some bounds on some particular constants of above types.
